Random country code returned for address with locale `en-US`

Looks like `address` generation got broken in version `1.14.0`

```
@Test
fun address() {
    // 1.14.0 - broken
    // 1.13.0 - works
    val faker = Faker(
        fakerConfig { locale = "en-US" }
    )
    val address = faker.address
    assertThat(address.countryCode()).isEqualTo("US")
}
```

```
expected:<"[US]"> but was:<"[AF]">
Expected :"[US]"
Actual   :"[AF]"
```
