Title: Fixed bug where dialogDidCancel wasn't getting called when Cancel button pressed

Pressing either the Send or Cancel button on the Request Dialog would always result in the dialogDidComplete delegate method being called. This changes it so that when the Cancel button is pressed, the dialogDidCancel delegate method is called instead of the dialogDidComplete.

Thanks!
