Editor crashes when Oculus boundary component is added without a HMD connected.
This was discovered while researching a separate bug report. A user stated that on a project that had been upgraded from 4.17 to 4.18 they were having crashes with OnTick using the boundary component when there is no HMD connected.
Results: The editor is crashing when adding an Oculus boundary component when no Oculus HMD is connected.
Expected: The boundary component should be added without crashing the editor.
