Inheritance abstract pages improvement

Reproduction path:
With an abstract page definition (abstract-standard-common) and a second abstract page definition (abstract-standard-common-mini-footer) that inherit from the abstract page definition. In the second abstract page the footer is overridden from the inherited. See attached image page_structure.png.

Result:
The correct footer is rendered. But still both subnodes footer-menu and footer-disclaimer from the abstract-standard-common are executed (known because POSSIBLE WASTE DETECTED messages in the log)

Expected result:
Only the footer component of the abstract-standard-common-mini-footer is executed.
