[Maposmatic-dev] [PATCH] Bug fix: check for wkt!=None in ocitysmap2/__init__.py:_get_geographic_info()

[David MENTRE]

In ocitysmap2/__init__.py:_get_geographic_info(), when one is looking in
the database, the returned "records" can be "[(None,)]". In that case
wkt obtains value None, which breaks the "shapely.wkt.loads(wkt)" call.
We add a protection against that.
