postpone loading the members until the user joined the room

Browse source 
when peeking, the members weren't being loaded at all because
the room wasn't available yet,
and the need for loading the members was never re-evaluated after that.

This only loads the members once the user has joined the room,
which also helps to avoid load all the members before an invite
is accepted.
