Improve handling of unsupported resolutions (#1804)

* Improve handling of unsupported resolutions

Adds a check in VirtualDisplayEncoder for unsupported resolutions that makes the virtual display encoder fail to start, prints a more helpful error message, and propagates an exception to the video stream manager
Changes in VideoStreamManager now kill the video stream service when the encoder fails to start, allowing for subsequent streams to start after an encoder error

* Add missing spaces to if statements
