Server Goes Into Bad State When Client Disconnects

[damaestro]

When a client disconnects without starting video the server goes into a bad state and is no longer able to be connected to.

ERROR [run] Exception in network thread: Socket shutdown

Reproduction steps:

• Start the server
• Connect the HMD client to the server without an OpenXR application running, the client enters the "waiting for video" state

To trigger the bug do either of the following:

• Click "cancel" on the client
• Close the HMD app through the android platform
