Stop spurious APIFormat stopwatches logs (#20008)
If there are dangling stopwatches with missing issues there will be repeated
logging of Unable to APIFormat stopwatches. These are unhelpful and instead
we should only log if the error is not an issue not exist error.

And we should also prevent an error on missing issue in GetActiveStopwatch too
