clearQueue() not setting queue size to 0

### Select which package(s) are affected \@livekit/rtc-node ### Describe the bug ### Expected After calling `clearQueue()`, I expect `queuedDuration` to be 0. ### Current After calling `clearQueue()`, `queuedDuration` does not get set to 0. ### Reproduction ```typescript // capture some frames... audioSource.clearQueue() console.log(audioSource.queuedDuration) // this will not be 0! ``` Can be avoided using a workaround: ```typescript // capture some frames... void audioSource.waitForPlayout() audioSource.clearQueue() console.log(audioSource.queuedDuration) // this will be 0 after `waitForPlayout()` returns ``` ### Logs ```shell ``` ### System Info ```shell not relevant ``` ### LiveKit server version LiveKit cloud ### Severity serious, but I can work around it ### Additional Information _No response_
