Reviewed by Chris Dumez.
As part of running the close steps for byte tee, we call close on the stream
branch1 and branch2.
Closing might throw an exception in case we have started to write data in an
ongoing byob request.
We need to stop executing the close steps in that case, which will prevent the
ReadableByteStreamController::respondWithNewView call.
We do this after closing both branches of the tee.
We also fix ReadableByteStreamController::shouldCallPull as a fly-by fix.
