Fix context menu focus for Edge downloads (#15300)

Fixes #14916

Summary of the issue:
When opening the context menu from the Edge downloads window, NVDA doesn't reflect this.

Description of user facing changes
Context menu is read again.

Description of development approach
It looks like the context menu items aren't direct children of the foreground window, therefore we compare the root of the foreground and the root of the focus window instead.
Fixed a typo in a UIAHandler debug string
Ensured that UIAHandler.getNearestWindowHandle returns when a cached window handle couldn't be fetched from an UIAElement due to a COMError.
