Subject: [PATCH] tst_QAbstractItemModelTester: fix mem-leak

QThreeWidgetItems that have been removed from their parents (or the
widget) must be deleted manually. The treeWidgetModel() test forgot
that, driving asan nuts.

Code predates the beginning of the public history, so picking to all
active branches.
