Render Title for Name in Transclusion per Default

In case a transclusion renders the name of the transcluded document as a header, the macro assumes that the referenced page is a projectdoc document. If it is not a projectdoc document it has no name and no heading will be added.

In case there is no name property, the macro should render the title instead. This also makes it easier for users to spot a configurations that do not align to the intended specification. Otherwise the heading would simply be missing.
