Description
When referring to a proxy model as a FK in a select_for_update() call, the proxy model's table is silently omitted from the FOR UPDATE clause in the resulting SQL.
Also, if a model has a FK to a proxy model, the FieldError that is supposed to be raised when an any inappropriate field is found in a select_for_update() call will crash with AttributeError: 'NoneType' object has no attribute 'name' .
Tested with postgres but I don't think this is specific to that db.
