Emitting an event within a `EventEmitter#once` callback of the same
event name will cause subsequent `EventEmitter#once` listeners of the
same name to be called multiple times.
var emitter = new EventEmitter();
emitter.once('e', function() {
emitter.emit('e');
console.log(1);
});
emitter.once('e', function() {
console.log(2);
});
emitter.emit('e');
// Output
// 2
// 1
// 2
Fix the issue, by calling the listener method only if it was not
already called.
