Occasional error occurs on commentary stop

[joshjaysalazar]

Describe the bug Due to what I believe to be a sync issue between threads, an error is occasionally thrown after stopping commentary because commentary is continuing to attempt to generate after the connection to iRacing has already been severed.

To Reproduce Steps to reproduce the behavior:

1. Start commentary on a replay
2. Stop commentary right as it is in the middle of generating new text

Expected behavior It should just throw away that commentary line and not throw an exception.
