[mutter/wip/smcv/no-test-environment] tests: Don't use TestEnvironment

    tests: Don't use TestEnvironment
    
    The specification for installed-tests says it's an overlay onto the
    current environment, but the implementation in gnome-desktop-testing
    currently removes all other environment variables, causing test failure
    (see GNOME/gnome-desktop-testing#1).
