Crashing application on incorrect user key

[DanrwAU]

Library is not returning err correctly when incorrect user key is set.

Code we're using to send messages

p.send(msg, function (err, result) {
              if (err) { logger.main.error('Pushover:' + err); }
              logger.main.debug('Pushover:' + result);
              callback();
            });

Results in a crash with an unhandled exception

From what i can tell this only started happening in later versions.
