Don't check flagLoaded for outbox message list

We found a case where messages in outbox have flagLoaded=FLAG_LOADED_UNLOADED,
where it should be FLAG_LOADED_COMPLETE.  Haven't found the root problem, but
remove the flagLoaded test to mitigate the problem.

Also moved the buildMailboxIdSelection call to a worker thread.
(this method issues some queries.)
