Correctly save the country code attribute
when storing JSON to the place store.

In some cases, when running in a different locale
compared to last run, the native name label could
still be shown with the native name from before
even when the primary name would become identical.

Flag coordinate-based places used for
the route from/to/via menus to not be
stored in the place store. As these
places contains no names, it makes
no sense, and it actually isn't
supported by the place store and
gives a GtkListStore warning.

We previously never had different attribution logos for
the map sources. Fix this so that it actually works
to update the logo when switching source now that
we use different providers for street and aerial.

Update the fallback service file with the
corresponding changes as the downloaded one.

Increase maximum width a bit to
allow place for the directions button
in some translations.

Safe-guard agains setting the aerial tile source
if it's not available in the service file.
This avoid a crash if aerial was saved as last-used
map type in gsettings and at next startup the service
has dropped support.

As we have disabled the aerial tiles, hide these
shortcuts from the overlay. But keep the definitions
so we can keep the strings translated when enabling
these when we get aerial back.

Only enable the shortcuts to switch b/w street and aerial
map types when aerial tiles are available.

As we have removed the dark and aerial tiles from the service
file, also remove them from the fallback (used when the online
one is unavailable).

Use the correct value '1' instead of 'yes' when posting
the authorization form. This fixes a regression making
OSM OAUTH setup to break with recent updates on
openstreetmap.org breaking the old incorrect behavior.

Fixes #386
