Fixed common abort while searching through some maildir folders.  It appears that (at least in the trash) some individual messages return true to 'isMessage' and some dont'.  Both are perfectly valid, though. However, there was this code in getMsgString
Fixed common abort while searching through some maildir folders.  It
appears that (at least in the trash) some individual messages return
true to 'isMessage' and some dont'.  Both are perfectly valid, though.
However, there was this code in getMsgString

  assert(mi!=NULL && !mi->isMessage());

which is obviously a holdover (copy-n-paste) from the mbox code.  I
just removed the '&& !mi->isMessage()' part since it is no longer
necessary for maildir.  Now no apparent crash!
