Unify creation of links to entity pages

[OmarHawk]

so that everywhere entityPage is being used as attribute

I noticed that the only place where the links to entity pages are being created differently is in the entity detail page. Everywhere else (e.g. list view), entityPage is already being used.

So this change improves consistency in the code base and also makes it easier for e.g. Blueprints to change something here consistently (that's why I came here ;-))
