Done handlers not called if promise already resolved

[MontakOleg]

This code will print 5:

let promise = Promise<Int>(queue: DispatchQueue.global())
promise.done { result in
    print(result)
}
promise.resolve(5)

But this is not:

let promise = Promise<Int>(queue: DispatchQueue.global())
promise.resolve(5)
promise.done { result in
    print(result)
}

This behavior is by design?

@MontakOleg Yes, this is by design as far as I remember. Could be improved though.
