Malformed URLs when using nested collections

[dri-richard]

(release 4.1.0)

If a screen proxy is in a collection which is in another collection, then its transition_url / focus_url / receiver_url properties are malformed, and the code to detect them in monarch.lua register_proxy() won't detect them.

To reproduce:

• Create a collection file called e.g. advanced_parent in folder example/advanced
• Add advanced.collection to the new collection
• Set advanced_parent.collection as the main collection in game.project
• Set a breakpoint in init() of screen_proxy.script
• Run
