ref(replay): Refactor replay for mobile touch start/end parity check

[ryan953]

Instead of doing this check inside the VideoReplayerWithInteractions constructor i just moved it up one level to the react component that creates that new instance, and wrapped it into a hook because react.

It was previously guarded by:

      if (root === null || isFetching) {
        return null;
      }

      // check if this is a video replay and if we can use the video (wrapper) replayer
      if (!isVideoReplay || !videoEvents || !startTimestampMs) {
        return null;
      }

and now we're just guarding the check with:

    replay: isFetching ? null : replay
    ...
    if (!replay || !replay.getVideoEvents()) {
      return;
    }

But it'll run at the same time as before: once whenever the replay is fully loaded.
