make savemessagelabels honor utime_from_header

Browse Source 
Previously, syncing labels on a message always resulted in updating the
file modification time, even with utime_from_headers=true

This patch restores the file mtime to the previous value when
utime_from_headers=true, preventing a label synchronization from
breaking the promise that the file mtimes coincide with the header date.
