Ensure the 'internal' flag is respected when calls to stop() function are enqueued

[tomdixon]

Issue/Feature

I discovered a race condition when a looping HTML-backed clip would call stop() internally (when the clip naturally ends) and if the playLock happens to be true at that exact moment, then the stop() call gets added to the queue. However the internal flag was being dropped, which meant that I was then erroneously getting an onstop callback when the looping clip restarted.

None I can find

Solution

The solution is to pass the internal flag on to the enqueued stop() function.

Reproduction/Testing

I was able to reproduce reliably by starting several short looping clips in quick succession. At some point, if you log out the onstop callback, you'll see it being called when one of the clips reaches its end.
