Fix not awaiting forward task

[martin-purplefish]

Really just wrapping in a try block!

This would cause errors like:

{"message": "Task was destroyed but it is pending!\ntask: <Task pending name='Task-124' coro=<TTSSegmentsForwarder._main_task.<locals>._forward_task() running at /app/.venv/lib/python3.12/site-packages/livekit/agents/utils/log.py:16> wait_for=<Future pending cb=[Task.task_wakeup()]>>", "level": "ERROR", "name": "asyncio", "pid": 1923, "job_id": "AJ_VKu3CSTZGMS9", "timestamp": "2025-01-06T18:11:34.516550+00:00"}

Fixes: #1264
