courts-db Lookups fail on courts' own citation strings

For example, looking up "W.D. Wash." fails to find wawd, even though "W.D. Wash." is that court's citation_string.

When I add the exact same value as the court's own citation_string to the test examples, that test fails. A line with "W.D. Wash." is inserted as an example:

    {
        "case_types": [],
        "citation_string": "W.D. Wash.",
        "court_url": "http://www.wawd.uscourts.gov/",
        [...]
        "examples": [
            "W.D. Wash.",
            "United States District Court Western Distict of Washington At Seattle",
            "United States District Court For The Western Division of Washington",
            "United States District Court Westhern District"
        ],
        "id": "wawd",
        [...]
}

I ran into this trying to convert Brad Heath's format (e.g., here) to a courts-db id.
