Added another container to cover a case where a resource is not at the end of the dependency graph. A Singleton provider type is arbitrary - its type doesn't play any role in injections, just needed something for a Resource to depend on.

I have in mind a few potential test cases that could be added: when there are no resources in the dependency graph; and when there are several different resources. |

Hello @jazzthief. Fix not working for several Resources. Maybe something like this?
Suggested change
| return {str(id(arg)): arg} | |
| closing_deps |= {str(id(arg)): arg} |
