Remove require for geofield_map in composer.json

Hello Jonasanne

I have reviewed your MR and it seems that it is removing the dependency from composer.json

Moving the issue to RTBC and wait if others to review

I couldn't test it by now, until next week I cannot check it out, but I could merge the MR if you can tell me please if geocoding is working as it should without any map in form , also if there's any error or message in browser console when trying to geocode any address.

I think that it must not depend on geofield_map module because geocoding must work without it, but maybe it tries to refresh something there...
