If the source never sends the push flag, WLED buffers the update but never publishes it to the LEDs. This causes the confusing case where the peek display shows one thing but the LEDs themselves something else. Add a static flag that tracks if we've seen a push from the source; until we do, apply every update as soon as it's received, per the DDP specification.
