Stop testing wind interpolation and fix FlightPlanningDomain

The webservice used to download weather is  not completely reliable and
makes the tests fail more and more often. So we stop try to download
those data.

When not relying on weather_interpolator, dISA was not defined so we set
it to 0., assuming standard atmosphere.
