[gtk/matthiasc/for-master: 2/3] Fix leaks in tests

[Matthias Clasen <matthiasc src gnome org>]

commit 168c1f440dee0feb811a04e0b4ab913ecd4a0146
Author: Matthias Clasen <mclasen redhat com>

    Fix leaks in tests
    
    All the list model tests were leaking items,
    because g_list_model_get_item is transfer full.
    
    Fixing these unveils a crash in the treelistmodel
    and maplistmodel tests.
