Remove relations for remotes (#5455)

For remotes, we will only create the foreign key, without the relation
metadata. Expected behavior will be:
- possible to create an activity. But the remote object will not be
displayed in the relations of the activity
- the remote objects should not be available in the search for relations

Also switched the number settings to an enum, since we now have to
handle `BigInt` case.
