Table name not aliased properly in WHERE subselect

[taylorhughes]

I have a test case: taylorhughes@0ed47fc

That causes the following error:

LOG:  statement: SELECT "tests_compositebitfieldtestmodel"."id", "tests_compositebitfieldtestmodel"."flags_1", "tests_compositebitfieldtestmodel"."flags_2" FROM "tests_compositebitfieldtestmodel" WHERE "tests_compositebitfieldtestmodel"."id" IN (SELECT U0."id" FROM "tests_bitfieldtestmodel" U0 WHERE NOT (U0."another_name" =  ("tests_bitfieldtestmodel"."another_name" | 2)))
ERROR:  invalid reference to FROM-clause entry for table "tests_bitfieldtestmodel" at character 312

The issue is that the WHERE condition should be updated with a new aliased table name, "U0" in this case. This has something to do with the django field method relabel_aliases(), I think, but I can't track it down exactly.

If someone can explain how to fix it I'm happy to build and test a fix, but I'm not too familiar with the depths of django here. :)

Also I should say I attempted to handle a relabel_aliases() in BitQueryLookupWrapper, but at the point where I could trace things through, it seemed like the filter value was still a Bit. Adding the alias map handling into the Bit itself seemed dirty, so, not sure where things should go...
