Option allow_playback_repeats doesn't work on record

[pyoor]

It appears that the allow_playback_repeats option doesn't work on record (though I'm not sure if that was intended).

The following test will record two requests when first creating the cassette.

def test_multiple_requests():
    with vcr.use_cassette('cassettes/cassette.yaml', allow_playback_repeats=True) as cass:
        response1 = requests.get("http://example.com")
        response2 = requests.get("http://example.com")

        assert response1.status_code == 200
        assert response2.status_code == 200

This could be fixed by modifying the following:

vcrpy/vcr/cassette.py

Line 250 in ce27c63

return request and request in self and self.record_mode != RecordMode.ALL and self.rewound

To something like:

return request and request in self and self.record_mode != RecordMode.ALL and (self.rewound or self.allow_playback_repeats)
