    Use instance.project_id when creating request specs for old instances

    The online data migration routine to create request specs for old
    instances is using an admin context, which doesn't have a project_id
    set, which means the request spec that gets created doesn't have
    a project_id set, which matters when the FilterScheduler tries to
    claim resources (create allocations in Placement) using said
    request spec's project_id (PUT /allocations requires a non-null
    project_id).

    This fixes the online data migration by creating the request spec
    using the instance's project_id rather than that from the context.
