Fix: Gracefully handle invalid sync times

The `SIMPLENOTE_SYNC_TIMES_KEY` was not guaranteed to be an integer. This commit handles this case by resetting the sync times to 0 if it is not an integer. This prevents a crash and ensures that the sync process can continue as expected.

The `TypeError` has been commented out, as it is no longer necessary.
