Flush logs when crashing.

When the process is running, we use a finally block to call Log.Dispose and flush any outstanding logs to disk before the process exits. This works when we handle any exception in a matching catch block.

When the exception is unhandled, then the finally block will not run and instead the process will just exit. To fix this, flush the logs inside a catch block instead before rethrowing the error. This ensures we get logs even when crashing.
