The address element should strip trailing whitespace from input

I wonder if this could be solved super generic by this thing that @mglaman wrote :D

#11 is working for for NL Postal codes here.

Added test for address validation with test cases for valid, valid with whitespaces and non-valid addresses.

With this being such a widespread problem, I think it needs a more generic solution than just a trim in Address.

I've just tested https://www.drupal.org/project/trim → , which has a stable release and works on all fields, including Address fields.

I think it's wise to point people to it.

Thank you everyone for exploring this problem.
