Remove map page in debates

The map feature was never implemented for debates (only for proposals
and budget investments) and it was crashing for debates because the page
didn't load the geozones. And we don't have a "geozone" field in the
debates form either.

So we're removing the map page alongside its (pending implementation)
tests.
