test: add test for tmpdir.refresh() failures on Pi
Raspberry PI devices in CI fail if tmpdir.refresh()
is called twice
and the tmpdir is not empty on the second call. This probably has
something to do with the tmpdir being NFS mounted. This is a
work-in-progress and this commit message should be updated once this is
fixed.
