Fixes bug 1110003 - Correctly remove namespace from returned results.

@peterbe r?
We are discussing some crappy code that is deprecated and will be removed in 2015q1. Note that this class is testing against Elasticsearch but is not an integration test (no nose ``@attr``, no mocking), and note that it has only one test. This truly is bad, but instead of fixing it here and now (this is supposedly frozen, I am currently fixing a pretty important bug that prevents people from the crashkill team to work), I have already made it a lot better in the upcoming ``es`` module, that will replace this one. You can see the code in this pull request: https://github.com/mozilla/socorro/pull/2510/files

Please let's not bike-shed too much on this. :-)

And to actually answer your question: yes, all tests do need the Super Search Fields to be populated, because Super Search cannot do anything without that data.
