Subject: [PATCH] Stop warning about no session from ViewerStats if user
 teleports to another region in the same simulator that was not next to the
 source region.

This was because teleporting to the new region invoked the new session setup code before the agent was removed from the old region, which then invoked the session teardown code.
Now, we only invoke the teardown code if the region ID occupied by the agent being removed is the same as the one registered for the current session.
