print("Clearing the cache") during tests

[agateau-gg]

Describe the bug

Since 5.2.4, when pyfakefs clears its cache, it prints a "Clearing the cache" message, which looks out of place in the pytest output.

How To Reproduce

Given a dummy test file like this:

def test_foo():
    pass


def test_bar():
    pass

And pytest and pyfakefs in a new virtualenv

~/src/pyfakefsbug 
$ pew mktmpenv
created virtual environment CPython3.10.12.final.0-64 in 242ms
[...]
~/src/pyfakefsbug py3.10.12 (2d92154d397a2df) 
$ pip install pytest pyfakefs
[...]

When I run pytest, I see a "Clearing the cache" message at the end:

Ah, sorry - that was a leftover from testing that I obviously missed, will fix this. Not sure if it's worth an extra patch release though... but then releases are cheap.

Thanks! It's not a show stopper for me, I can live with it until there are enough changes for a future release :)
