Improve integration tests

[batiati]

While investigating this Rafik issue, I noticed that our Node.js CI passes even if tests fail.

• Ensure that the Node.js test runner returns a non-zero exit code when tests fail.
• Add Node, Java, and Dotnet tests for pending_transfer_expired.

Failure seems legit:

    Failed CreatePendingTransfersAndVoidExpiredAsync [6 s]
    Error Message:
     Assert.IsTrue failed. 
    Stack Trace:

Failure seems legit:

Looks like Task.Delay does not have accurate resolution and sometimes finishes sooner than the timeout 😨.
Kind of the same problem here: WalletWasabi/WalletWasabi#6166
