fix updating cached message flags in imap_set_msg_flags()

Browse Source 
while this (currently) doesn't really matter (as all flag changes are
calculated before any are actually submitted), msg's flags should not
be updated before set_msg_flags() has actually succeeded.

as a side effect, this does away with the redundancy elimination and
pulling uid from msg (which were both unused since 19128f158).
