* Add more files plugins to new DAV endpoint
Also fix report plugin to properly retrieve the path from the
prolongated URL
* In case the report is not for this plugin -> simply return to allow other plugins to get executed
* Adjust onReport tests to match new behavior
Enhanced the REPORT method on the Webdav endpoint and added a
"oc:favorite" filter rule. When set, it will return a flat list of
results filtered with only favorite files.
The web UI was also adjusted to use this REPORT method instead of the
private API endpoint.
