client: ignore APP_CMD_PAUSE/STOP if it occurs before APP_CMD_INIT_WINDOW
This makes the android studio debugger work. Previously the app received APP_CMD_STOP, killing the connection right before the promise in emconn_webrtc_on_answer_created was populated.
The only reference I found was in the release notes for unreal engine 4.26 https://docs.unrealengine.com/4.26/en-US/WhatsNew/Builds/ReleaseNotes/4_26/
Bug Fix: Oculus now ignores the app command APP_CMD_PAUSE if it occurs before APP_CMD_INIT_WINDOW.
