"".split(" ") returns [""], so we're creating adding a "WHERE (url LIKE '%%' OR title LIKE '%%')" clause to empty filter queries. Let's not do that.

I modified testBrowserProviderPerf to run with an emtpy filter string (see bug 785945 comment 9), and here are some results:

Without patch: 1344, 1341, 1356 
With patch: 1276, 1269, 1258

We'll still want to continue to work on fixing this query in bug 785945, but this is a really simple win that we could probably uplift.
