Sync and set active room when joined only in Application

"syncAndSetActiveRoom" in Embedded only synchronized the rooms after
joining a room, but that is already done in PublicShareAuth and the
Files plugin (followed by some specific code for each case once the
synchronization is done). Due to this calling "syncAndSetActiveRoom"
after joining a room is only needed in Application.
