statistics should check params of GeocoordinatesMapping

[VladimirAlexiev]

http://mappings.dbpedia.org/server/templatestatistics/bg/?template=Селище_в_България says that 98.37 % of all property occurrences in Wikipedia ( bg ) are mapped. So we should be very happy.

Then how come BG settlements have no cordinates? Checking the mapping http://mappings.dbpedia.org/index.php?title=Mapping_bg:Селище_в_България&action=edit I see that someone made a mistake and used the wrong template params (instead of latitude, longitude):

{{ GeocoordinatesMapping | latitudeDirection = сев-ширина | longitudeDirection = изт-дължина }}

The extractor produces nothing in this case. But I think the statistics module should check that the set of params used in a template is meainingful, before counting the respective template properties as covered.
