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

[Matthias Clasen <matthiasc src gnome org>]

commit 9e50bc74fae812a656f559a9f707bd282b2b33fa

    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.
