Fix heap-use-after-free in Container when using ListView transitionsHEADdev

Container's removeItem function removes and deletes items immediately.
This has caused issues in the past, like QTBUG-46798. QTBUG-133256 is
similar to that, except it also involves transitions.

This patch fixes the crash by listening for the destruction of items
created within an ObjectModel and removing them so that views don't
have dangling pointers to them.

Add removeAndDestroyObjectModelItem to tst_qquicklistview2, which is
similar to the test added for 1e3924d8f585dd9099eb74ffbc17950c693d14da
but adds more thorough checks and transitions.

Fixes: QTBUG-133256
