"Change Scene" button is missing once the scene is set from a GLB

[rawnsley]

Once a custom GLB URL is used to set the scene for a room, the scene cannot be set again to either an existing scene or another GLB URL.

This is particularly restrictive when rapidly iterating new scene files as you have to create a new room for each scene version.

Thanks! I definitely noticed that one when testing locally once but forgot to file it.

I have verified this issue using Firefox 89.0 and Chrome 90.0.4430.212 on Windows 10.
Now, the "Change Scene" button is present for the rooms created with the GLB scenes. An interesting thing I notice is that the original issue is not present on Hubs Cloud.
