If marge doesn't find deqp-runner results or trace errors, she will parse a failed job log for error messages. The parsing ignores certain phrases in an attempt to find more relevant errors. Add a test to check marge's error log parsing to make sure that we don't create regressions when adding new phrases to ignore.
