    Workaround missing RequestSpec.project_id when moving an instance

    The online data migration routine to create request specs for old
    instances used an admin context which has an empty project_id,
    so when scheduling (moving) one of these, if we try to PUT /allocations
    in placement using the FilterScheduler we'll fail because the project_id
    is None.

    This works around that by putting the instance.project_id on the request
    spec before calling the scheduler to pick a node and claim resources
    against it.

    A later change will need to add some sort of online data migration
    routine so that we properly update and persist the fix for these
    older records.
