The test suite does not pass locally because I use a custom
file_link_format. I do it because it works everywhere.

Then, Symfony tries to read this value before the default one.
We could use ini_set before the test but unfortunatelly there are no way
to define the "cfg_var". For recall, get_cfg_var allows to return the
configuration value even if the extension is not loaded. And again it's
my case: I don't enable xdebug to have better performance.
