Option `allow_playback_repeats` doesn't work on record

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: https://github.com/kevin1024/vcrpy/blob/ce27c636857b49c71e9a3ffe0f0bee9135fba181/vcr/cassette.py#L250

To something like:

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