watch: flush changes to inbox before updating IMAPTracker

Data needs to hit inboxes, first.  Otherwise it's possible to
skip messages in case git-fast-import is killed before it sees
"done\n".  Now, -watch will just waste a little bandwidth in
re-downloading a seen message if it's interrupted immediately
before updating IMAPTracker.
