* Update sabre/dav to 3.2.0
* Adjust code to work with sabre/dav 3.2.0 and it's dependencies
* Adding own CalDAV plugin to fix calendar home property
* Test if there is a user logged in when listing files home
* Update sabre version used by integration tests
* Disable unauthenticated DAV access
This is needed to make Sabre 3.2 behave like we did before.
Eventually we should integrate better with the ACL plugin which itself
should implement an auth failure when appropriate.
=====
* Fixed so cherry-pick was succesfull
