* Performance was very poor due to several reasons:
* City name translatable.
* Lack on indexes when deleting obsolete records.
* Some prefetching.
* City was not being searched also by state, having the chance of returning
incorrect matches if same city name on different states.
* Previous code was removing all previous records of zip entries!
* Remove possible obsolete FK keys after migrating from v11.
* [IMP] base_location: Add lat & long to `better.zip`
* Add latitude and longitude columns to `better.zip`
* [IMP] base_location_geonames_import: Add lat/long
* Add support for latitude & longitude to genomes importer
[IMP] base_location_geonames_import: Make tests more efficient
[FIX] base_location_geonames_import: Don't alias Warning
[IMP] base_location_geonames_import: Convert tests to Python + switch imported country
Monaco country is very little and it allows to save some downloaded bytes plus making
a test for entries deletion
[IMP] base_location_geonames_import: Switch author
[FIX] base_location_geonames_import: Fix test
[FIX] base_location_geonames_import: Fix tests
[MIG] Make modules uninstallable
[MIG] Rename manifest files
[FIX] base_location_geonames_import: Test logic changed
For avoiding constant problems with this test, as Monaco data changes a lot,
what we are testing now is the existence of the data, not the exact match of them.
