Introduce the '--migrate-fmd5-using-nametrans' option which migrates the FMD5 hashes from versions prior to 6.3.5. It seems that commit 'Apply nametrans to all Foldertypes' (6b2ec956cf) introduced a regression because it changed the FMD5 part of the filename calculated by OfflineIMAP. Thus, OfflineIMAP believes that the messages has been removed and adds them back.
