hipchat import: Fix bug w/rogue UserMessage records. 

This bug was introduced very recently and is an
aliasing bug.  It caused extra UserMessage rows to
be created as we inadvertently updated the underlying
subscriber_map sets for multiple messages.

This probably mostly affected PMs.

It's doubtful the bug ever got out into the field.
