New description:
`ForeignObject`'s implementation of `get_lookup` and `get_transform`
causes `register_lookup` to essentially have no effect.
The PR should allow users to successfully register lookups while ignoring
the default lookups registered to `Field`. This works by duplicating
`RegisterLookupMixin._get_lookup`, but stopping mro walking at
`ForeignObject`.
