    profile-migrator: Fix migrators maybe not running for default profile
    
    Problem is, Epiphany creates the new profile dir with current migration
    version if it does not exist on startup, BEFORE running the migrator. So
    all migrators are guaranteed to never run if ~/.local/share/epiphany
    does not exist. This makes testing migration really hard.
    
    Still, this would probably not be a problem for most users, since they
    will have local storage and databases stored here already.
