    Add filter for soft-deleted instances to periodic cleanup task

    The periodic cleanup task added recently does a db query to get
    instances in need of cleanup. The filters applied to the query
    must have a filter to not include soft-deleted instances.

    This fix adds the required filter and adds a test to verify the
    correct behavior.
