libgweather string change that doesn't affect you

[Dan Winship <danw gnome org>]

I just fixed #548630, which removed two strings from libgweather, and
#549047, which added back a string ("Guadalajara") that was present in
2.22 but had been removed in 2.23. Then I updated all of the affected
translations (using the translations of that city name from 2.22). So
this shouldn't actually affect anyone.
