    ephy-profile-migrator: do nothing if there's no profile dir
    
    If there's no profile dir there should not be anything to do for the
    profile migrator (since in theory epiphany has never been
    executed). This might backfire for people that manually mess with
    their profile dir (removing it), but those people hopefully know what
    they are doing.
