Do not validate phone numbers from other regions

I'm unsure whether this is a bug in "libphonenumber-for-php" or if we're
misusing the library. This commit will ensure that only phone numbers
from a specific region will be considered valid. I've reported the issue
to "libphonenumber-for-php" anyways [1].
