NodeJSCTests unit testing target fails

[balazserdeszlogmein]

macOS 15.5, Xcode 16.4

There are failing unit tests for some reason in the NodeJSCTests target.

The first test succeeds, but the second one always fails with the same message:

terminating due to uncaught exception of type std::runtime_error: NodeAPI/NodeActor.swift:43: There is no target NodeAsyncQueue associated with this Task, and there is no global default queue.

[kabiroberai]

This should be fixed by #54, can you check if that makes the tests pass for you?

There’s been a lot of thrash around executors in recent Swift releases, my most recent fix made it so things work a lot more reliably if you only have a single NodeSwift environment (eg no background workers) but the tests spin up multiple which requires a separate solution like the one in the aforementioned PR.

That does fix it, thank you!
