Tests fail silently if they have the same name as other tests #447

We have a suite which has a number of tests named "Happy Path".

We recently discovered that if some of them fail, then the test run still exits with a zero exit code, and our CI build passes.

This seems to be a result of this code-
https://github.com/Codeception/CodeceptJS/blob/master/lib/listener/exit.js#L19 - which removes a test from the failures list if a test with the same name later passes.

I'd recommend doing something a bit stricter than purely name matching in this case (possibly name + file, or generating a unique id for a suite/test) so that it is not possible for test failures to be ignored.

Happy to PR if you have a preferred approach.
