[mutter/wip/smcv/no-test-environment: 49/50] tests: Don't use TestEnvironment

[Simon McVittie <smcv src gnome org>]

commit 85985630bff5153032fb62c3dd5d2ff4a6dcd101
Author: Simon McVittie <smcv debian org>

    tests: Don't use TestEnvironment
    
    The assumption here seems to be that it's an overlay onto the
    current environment which would make sense; but the implementation in
    gnome-desktop-testing currently removes all other environment variables
    (see GNOME/gnome-desktop-testing#1). This causes test failure when the
    tests are run in Debian's autopkgtest framework, possibly because PATH
    is cleared.
