detectSeries issues

[solarflare045]

There are two minor bugs with detectSeries():

• If the iterator function does not return a promise, the operation fails.
• The _notFound parameter is not passed through additional iterations.

Examples:
You would expect this to resolve to 3. Instead, this throws an exception.

detectSeries([1, 2, 3, 4], function(n) {
  return n > 2; 
});

You would expect this to resolve to 88. Instead, this resolved to undefined.

detectSeries([1, 2, 3, 4], function(n) {
  return n > 6;
}, 88);

Out of curiosity, why would you want to use detectSeries with a non-async iterator? Isn't that just the same as Array.prototype.find? (I agree it should be fixed for consistency; I'm just curious)

It is mainly to handle situations where the iterator sometimes returns a Boolean value, and sometimes returns a promise to resolve to a Boolean value.
