[IMP] website_google_map: display correct partner location on map

Currently, when the geolocation coordinates (latitude & longitude) of
the partner are not set, location for such partners is shown in the
middle of the sea (on /partners page).

With this commit, the coordinates are handled properly so that if they
are not set, instead of sending "0.0" to the map API, we now pass them
as a Falsy value, so that Geocoder API could use the available address
and locate such partners properly in the google map.
