[pygobject] Add tests for GFile

[Martin Pitt <martinpitt src gnome org>]

commit 60544b02f6f98c0b212625ae83b94a4c6debddeb
Author: Simonas Kazlauskas <simonas kazlauskas me>

    Add tests for GFile
    
    Most notably this commit contains a test for Gio.File.replace_contents_async(),
    which currently fails. Disable the tests for now as it breaks the other tests.
