[FIX] base: correct spanish address format

Commit 8889a896f introduced the state in the address format for spain
between parentheses, however if the state is unset this leads to weird
values like
```
Isabella López Navarro
()
Spain
```
which is bad.

This commit instead formats spanish addresses by adding the state below
the Zip+City line and above the Country, as suggested here:
https://en.wikipedia.org/wiki/Address#Spain

This avoids empty parentheses.
