[FIX] website_jitsi: fix participant count update

Bug
===

When we implemented `website_jitsi` we didn't need to enter a pseudo. Users
automatically joined the room. But now we have one more step about entering
Jitsi username. During this step the room can become full so we need to check
one more time if room reached its full capacity.

Correctly use the option `check_full` in `website_event_track_exhibitor`.

Do not wait for participant update if the room become full.
