AbstractNavitiaProvider: use full url for TripQuery

[ialokim]

As pointed out (some time ago) in this issue, AbstractNavitiaProvider does not add coverage information into the url when searching for a trip (on endpoint journeys), see here.

This does not cause any problems when there is no error as Navitia can handle queries without the coverage part. But in the case of an invalid station, it seems to make a difference: Navitia's returning a BlockedException instead of the invalid_station flag.

I guess this could be solved by simply adding the coverage part into the url as done in all the other methods (e.g. suggestLocations). They use the method url() which returns the base path including the coverage.

If you want me to do so, I could make the necessary change and open an PR.

I think we should add the coverage info to the URL.

Some thoughts on this @schildbach ?

I'm not an expert on the Navitia API. From your description, it sounds like a reasonable thing to do. Feel free to submit a PR.
