Behavior change from 1.4.21 to 1.4.22

Hi there,

I've got some unit tests for our project that started failing when we upgraded. Figured I would confirm the behavior change from #136 we noticed is what you expected.

Here is behavior with version 1.4.21

[2] pry(main)> TelephoneNumber.parse("20\" 555 1234").e164_number(formatted: false)
=> "205551234"

Here is the different behavior from 1.4.22

[7] pry(main)> TelephoneNumber.parse("20\" 555 1234").e164_number(formatted: false)
=> "20205551234"
