Removes dashes when locale and number is not NANP or Japan

Removes all dashes if locale isn't NANP or Japan and the number
don't have there country code.

Use case: If adding a number starting with 1nnnnnn and then
          trying to add a country code before (ex +46) we will first
          trigger NANP formatting with +1-nnn-nnn so when we get
          +41-nnn-nnn we will still have the old NANP formatting.
          This number should be shown as +461nnnnnn.
