Subject: [PATCH] Fixes #2216 -- Added extra tests for model validity, and
 cleaned up warning messages for existing tests. Models are now invalid if the
 query string required to access a field (or related object) would clash with
 the name of another field (or related object). Previous tests only checked
 the accessor names, not the query string.
