glib: Fix ptest race issue

gio/tests/portal: Fix test ordering race

When the gnome test runner executes the tests, the test appear to execute in disk
order. This means it sometimes works and we sometimes see breakage in portal-support-snap
and portal-support-snap-classic.

The issue is that some tests create config files but some don't. If they run
in the wrong order, tests see config files they shouldn't and break.

Fix this by deleting the files after each test run, properly cleaning up after
themselves. There are probably better ways to handle this but this patch should
at least let us check this is the issue.

I've tried to report upstream but their issue tracker account creation is struggling
and I can't get my account to work.
