This fixes collisions that were causing uploads to break in a very
terrible way.
Kudos to @kesselb for finding the problematic place and to
@hottwister for the proposed solution.
Fixes#10527.
When a single file was dropped on the trash bin the file information was
gotten from the original element in the file list. When several files
were dropped on the trash bin the file information was gotten from the
helper elements being dragged around. The helper element also contain
the needed file information when a single file is being dragged, so the
handling was unified to always get the file information from the helper
elements.
As the handling of several files is the same as before there is still
the issue of only deleting those files shown in the drag helper instead
of all the selected files.

The "droppedOnTrash" event was being triggered when the file list was
initialized, but it should be triggered only when the user actually
drops a file on the trash bin.
Besides that, the event had no effect; only the file list handles it,
but as it was not triggered on any element it ended being triggered on
the document, and thus not handled. Moreover, even if it had been
triggered on the file list it would have been done before the handler
was set, so it would not have been handled anyway. And even if it had
been handled no data was provided, so the handler would have failed.
In conclusion, triggering the event there was not needed, and thus it
was removed.

Since 6ad7f32938 SVG icons are directly embedded in "icons-vars.css", so
the starred trash icon is now loaded along with the regular trash icon
all at once. Therefore it is not needed to explicitly prefetch it using
a hidden div.

When the uploaded files have a relative path (that is, when a folder is
uploaded) it is first ensured that all the parent folders exist, which
is done by trying to create them. When a folder is created in the
currently opened folder the file list is updated and a row for the new
folder is added. However, this was done too when the folder already
existed, which caused the previous row to be removed and a new one added
to replace it.
For security reasons, some special headers need to be set in requests;
this is done automatically for jQuery by handling the "ajaxSend" event
in the document. In the case of DAV requests, if the headers are not set
the server rejects the request with "CSRF check not passed".
When a file or folder is dropped on a folder row the jQuery upload
events are chained from the initial drop event, which has the row as its
target. In order to upload the file jQuery performs a request, which
triggers the "ajaxSend" event in the row; this event then bubbles up to
the document, which is then handled by adding the special headers to the
request.
However, when a folder was dropped on a folder row that folder row was
removed when ensuring that the folder exists. The jQuery upload events
were still triggered on the row, but as it had been removed it had no
parent nodes, and thus the events did not bubble up. Due to this the
"ajaxSend" event never reached the document when triggered on the
removed row, the headers were not set, and the upload failed.
All this is simply fixed by not removing the folder row when trying to
create it if it existed already.
