Atomic update on uniqueKey field itself causes duplicate document

          Description

          Issuing an atomic update which includes the uniqueKey field itself will cause Solr to insert a second document with the same uniqueKey thereby violating uniqueness. A non-atomic update will "correct" the document. Attached is a JUnit test case that demonstrates the issue against the collection1 core in the standard Solr download.

            Obviously, the workaround is to make sure that you don't do an atomic update on the uniqueKey field itself (which I was sort of doing by accident anyway). I just don't think anything should allow the violating of the uniqueKey.

            Thanks Eric - I've changed UpdateTest to include this scenario and replicated what you see.
            I think the right thing to do here is probably throw an exception (rather than ignore the modifiers on the id field).
