    Properly handle shared storage in case of cold migrations

    At the moment, if the destination host is other than the source
    host, we attempt to move the instance files without checking if
    shared storage is being used.

    This change fixes this issue. In case of shared storage, we'll have
    the same workflow as when the migration source is the migration
    destination as well.

    Closes-Bug: #1565895
