Fix error about TestRtcPublish_HttpFlvPlay. v7.0.36 (#4363)

In the scenario of converting WebRTC to RTMP, this conversion will not
proceed until an SenderReport is received; for reference, see:
https://github.com/ossrs/srs/pull/2470.
Thus, if HTTP-FLV streaming is attempted before the SR is received, the
FLV Header will contain only audio, devoid of video content.
This error can be resolved by disabling `guess_has_av` in the
configuration file, since we can guarantee that both audio and video are
present in the test cases.

However, in the original regression tests, the
`TestRtcPublish_HttpFlvPlay` test case contains a bug:

5a404c089b/trunk/3rdparty/srs-bench/srs/rtc_test.go (L2421-L2424)

The test would pass when `hasAudio` is true and `hasVideo` is false,
which is actually incorrect. Therefore, it has been revised so that the
test now only passes if both values are true.
