Revert "Make delegates_item_empty_jscreation & delegates_qobject comparable"

These still weren't directly comparable (as they have different count
figures), and the change has been causing significant confusion when
examining results.

At the same time, we introduce apparently regressed QObject array benchmark as
a new test so we can track improvements in that area.

This reverts commit 45da7843d6c7b70ecd37c952fd68dd84f79c23e0.
