Description

Searching for Pershagen returns the following json
https://maps.googleapis.com/maps/api/geocode/json?address=Pershagen&key=xxx

Using the google maps provider I get the following object. The phrase Pershagen is omitted.

Searching for the similar area Ronna I get a more correct object.

When looping over address components Pershagen is first set but then overridden by Södertälje.

Reversing the array on L235 in GoogleMaps.php returns a more accurate result.

+foreach (array_reverse($result->address_components) as $component) {
-foreach ($result->address_components as $component) {

Not at all sure how this will affect other results!

Research direction

Start in GoogleMaps.php around line 235 and trace how address_components are mapped into the returned object. Reproduce the Pershagen and Ronna searches, then verify that the parsed name is correct for both cases and that other address-component results are not regressed.
