Remove remnants of replace booth (#667)

This was probably a nice idea we had back when üWave was first started.
A moderator would be able to instantly put a user in the booth, skipping
the waitlist.

In practice we never implemented it, and it would require client-side
support. I doubt it's all that useful and it is just dead code right
now.
