Make ContainerTree singleton but construct in run() of application 
We want to make sure that this tree is constructed during start-up after all containers have been registered, so we call getInstance() there once. If you need the tree before that, the tree will not yet have been filled and you won't get complete information, so you'd need to listen for updates.
The singleton is there so you don't need to go via CuraApplication.

Contributes to issue CURA-6600.
