[BUGFIX] Collect correct information on elements in page

In the page module information on neighboring content elements is
collected while building the page layout. This information must be
remembered for other elements on the page instead of generated new when
rendering each element. This makes sure the move buttons and edit
buttons have the correct URLs.
