[pygobject/ci-fix-gtk4-tests] tests: Make tests run with GTK4



commit 8425bd5016bc578ca81c3932e587aed41567cb44
Author: Christoph Reiter <reiter christoph gmail com>
Date:   Sun Nov 4 20:27:36 2018 +0100

    tests: Make tests run with GTK4
    
    This contains the minimum changes needed to get the tests to pass using our
    docker image which contains a build gtk master from today.
    
    This also makes the gtk4 CI job fatal so we don't regress in this area.
