Currently, the sample queues are lazily enabled when they are first read from. This causes problems when the player tries to discard buffer and the HlsSampleStreamWrapper assumes the sample queue is disabled even though it's actually enabled but hasn't been read from. This change moves setting the sample queue index of the sample stream back into HlsSampleStreamWrapper. It enables the sample queues at track selection if the queues are already built, or immediately after they have been built for chunkless preparation.
