Remove html tags from private messages in the home page, fixes #812

fix #774
We no longer need to update the recordings list from a room when the user is not logged in.
If the user is not logged in then we only select the data from the local database, we no longer synch with lb.
The error occured because the recordings needed an auth in order to work.
