When using addressfield, the country code is shown in location instead of full country name

If you use an addressfield for location, the generated address has the country code instead of the full country name.

For instance, given the following address:

John Doe
Sample Street 100
12345 Mycity
Germany

the generated location looks like:

LOCATION:John Doe\, 100\, Sample Street\, 12345\, DE

expected format would be:
LOCATION:John Doe\, 100\, Sample Street\, 12345\, Germany

I've created a small patch for that, please review.
