Performing a mongo $set: {} will fail on mongo 2.6+: https://jira.mongodb.org/browse/SERVER-12266

For now fix this only for the failing test case as it should not be an issue in the field for other

PEP-8 server.managers.repo.unit_association_query.

Also PEP-8 its tests. It turns out that we skip several of the tests in
