[BUG] - Rich Notifications Don't Work On iOS 13
**Describe the bug**

Since upgrading to the iOS 13 betas, motion sensor notifications no longer include still images from the camera in a room as a rich notification. This has persisted from beta 1-6. 

Home hubs are Apple TV HD / Apple TV 4k, both running tvOS13 Beta 6.

**Expected behavior**

On iOS 12.x, when notifications were enabled for motion sensors, it would include a still image from the camera in the room as a rich notification.

**Logs**

I didn't enabled debugging, as it appears this issue is on the iOS side of things. My Mac mini currently running 10.14.6 still receives images in motion sensor notifications, as well as my wife's iPhone running iOS 12.4.

**Desktop (please complete the following information):**
 - macOS 10.14.6
 - Node Version 6.9.0
