Missing variable error when stopping commentary

[joshjaysalazar]

Describe the bug Ocassionally, when stopping commentary, Python will complain about a missing value.

To Reproduce Steps to reproduce the behavior:

1. Start commentary
2. Stop it
3. See the error happen sometimes, but not all the time

Expected behavior Obviously shouldn't throw an error; I think there just needs to be a quick sanity check there to see if data is still flowing from iRacing at that point.
