Prevent use of the same array in CollectionProperty (close #58743)
CollectionProperty constructor receives an empty ObjectTableModel.objects
collection but normalizeList will return it as-is instead of creating a
new empty collection.
The two classes share the same array but add different kind of classes.
NOTE: Basically the bug is in AbstractProperty.normalizeList because it
should never reuse the same instance. I've done the patch as you see it because
it has the lowest impact and does not change the normalizeList API (perhaps
reusing is expected in some cases?)
Let me know if I should redo the patch by just changing normalizeList!
