Subject: Fix using Properties items in Groups.

In EvaluatorScriptClass, we overwrote the already existing outer item
with a (non-working) new one. The original intention of that code is not
entirely clear to me; my assumption is that it can continue to exist as
a fallback where "outer" is used outside a group.

Task-number: QBS-877
