Properly implemented JS GlobeCoordinateValue::toJSON and newFromJSON

Allows round tripping with the backend implementation now. Precision is not yet implemented.
Moved the problem of dealing with precision from globeCoordinate.js into GlobeCoordinateValue
since "globeCoordinate.js" should not really know or care about the problems of the "backend"
or anything else Wikibase related.
