Correctly implement interface for wrapper geometry.

[evetion]

Fixes evetion/WellKnownGeometry.jl#37.

Packages should implement the two argument interface methods for geometries, and #124 did not. In WKG I assumed I could call ncoord(trait, geom), which failed.

Beat me to it! Tests?

Yeah, precisely what? Hasmethod for the two argument function and implement that in testgeometry? That way we can re-use for other packages who implementend it incorrectly (might be breaking some tests somewhere else).

I mean just calling those methods with the trait somewhere or other, but certainly add to the generic tests if that makes more sense, we don't do that enough...

I've added tests (which failed on master) to the generic test implementation 🙂. @rafaqz, I think this is good to go now (also to fix WKG), are you ok with merging?

[rafaqz]

Would we not just call the methods?
