Fix notification setting resetting to 0

'0' and '1' are valid inputs in the config file but followed the
logic of the 'try' block and thus if the user set -1, it would
change to 0. With this change, '0' and '1' remain the same, and only
if the value is not either of them will the try/except block run.
