Comparing a newly created Coordinate claim with one fetched from Wikidata fails even if these are the same.
This occurs because _entity does not get initialised if globe is used during initialisation. Similarly if entity/globe_item is used globe would not get initialised.
The solution is to override __eq__ in a similar way to how this was done for WbQuantity or to rethink how we compare the different Wikibase claim types.
