Summary

When running jest with '--passWithNoTests' but there are no tests to execute, it prints a superfluous warning. This PR removes this warning.

Description

In both screenshots below there are no test files and jest is executed with --passWithNoOptions.
It used to log that it exited with code 1 and a message to use --passWithNoOptions, while it exits with code 0 and the option is already provided.

Closes #8594

Nice! Can you add a changelog entry and a small test?

Sure! I added a changelog entry and some snapshot tests. While adding the tests I found a simpler way to fix the issue so I'll have to force push the new changes.
