[gtk+] reftests: Make animation-direction test more reliable

[Matthias Clasen <matthiasc src gnome org>]

commit 5a2feab8c0e856ae3536817b8f120d0ff13bb623

    reftests: Make animation-direction test more reliable
    
    This test was failing in continuous, where the tests are running
    in a VM with disabled animations. Make the test adapt to that
    situation by changing the reference ui on the fly if we find
    that animations are disabled.
