fix(#2889): return always the same error contract from simplifyTest

[andremoah]

Motivation/Description of the PR

• Resolves Incorrect BDD Parallel execution background fail/success #2889

Currently using patch-package with this fix on version 3.0.7 and been testing since then. With the complexity of the core api of codeceptjs, I could not find a way to replicate the error by sending an invalid object with inspect and cliMessage functions on it like shown in the reported issue. I would be glad to add some tests if someone could point me on how to build these tests to track the exact problem.

Thanks! I didn't get if that actually fixed the problem but this refactoring makes sense
