Input and Application buttons not working
Hi, I have v4.1.1 working great, I am able to turn my Sony TV (Bravia XBR-65X750D) on and off and adjust the volume via HomeKit.  I love it!  

I just added **HDMI 2** as a TV input, and since this version of the plug-in successfully scanned for installed apps on my Sony, I added **VUDU** as an application too.  The buttons show up in HomeKit.  However, pressing them doesn't do anything.  They don't toggle off and they don't launch VUDU or switch to HDMI 2.  As far as I can tell, nothing's happening.

My Sony is a  homebridge-bravia-tvos 4.1.1 is setup using the Pre-Shared Key method. I left App Name and App UUID blank because I didn't know what to put there and the documentation seems to imply those are only necessary for the PIN authentication method.

Any pointers appreciated.  Thanks so much!
