[REV] Revert "[IMP] base: select countries & state based on exact code, (useful for import and fast many2one)"

This reverts commit 09a22e3bef663143c10a6e502f1f207cdf69aab2, which was
attempting to fix a use case that was actually working.
It also created a duplicate `name_search()` method for res.country, in
addition to the one aliased to `location_name_search()`

It is indeed supported to import countries and states, using the
country code or state code as the imported value. These will be matched
uniquely thanks to the special `name_search()` performed for import,
forcing the `operator`.
And this is done while still allowing proper auto-completing for normal
UI case, where the "exact code match" will only promote an extra result
at the top of the suggested matches, rather than limit the results to a
single match.

The confusion apparently stemmed from the test case using "UK" as the
country code. UK is not a valid ISO country code, so it would never
match as expected.
