This allows for query objects generated from `Baloo::Query::fromSearchUrl` to use the same URLs parsing as those using the kioslave.
Previously, only query urls with `json` format were available, while the kioslave could also parse the `query` keyword and simple type urls (e.g. `baloosearch://videos`)
This was preventing the file type to be updated for places panels' default search urls (e.g. `baloosearch://videos`)
