[jan] Fix installation path of \Sabre\VObject\Document.
Revert "[mms] Fix some cases where the seesion was not destroyed upon authentication errors."

This broke failed authentication if not using the UI, i.e. any RPC request that
handles failed authentication internally will now be redirected to the login
screen.

This reverts commit 38d83ff0c22491e8b3f5831bb03b0645e2b817f3.
