I suspected this wasn't necessary for awhile, but finally tried it and I can't
seem to find anything that broke when I removed it.

Fixes PIDGIN-17566

Connected a Bonjour account, set the status to away with a message, stopped Pidgin, verified that status.xml contained what looked correct, then restarted Pidgin and verified that the status was set to the previous status before exiting.
Added an XMPP account, set the status to do not disturb with a message, closed pidgin, verified status.xml looked mostly correct, then restarted Pidgin and verified that the statuses were set to the previous statuses for both accounts.
