Patch to the query regression test demonstrating the problem is attached. I'm pretty lost on getting a fix; it's in some hairy query code.

This looks similar to #9041. One of these could probably be marked a dupe.

(In [10136]) Fixed #9926 -- Fixes for some select_related() situations.

Using select_related(...) across a nullable relation to a multi-table
model inheritance situation no longer excludes results. Thanks to AdamG
for a test demonstrating part of the problem.
