Bug 1095097 - Override e.me url to localhost during tests. r=kgrandon

Minor nit, just looking at the rest of the Everything.me paths, it looks like there was an intended convention of putting this in the file path of the "object type". E.g., ```search_suggestions.json``` instead of ```suggestions.json```. Nothing that I'd block the review on, but you may want to update this to match the rest of the file (though maybe the rest of the file is no good).
