[ENHANCEMENT]: Use aggregation fieldsets by default

[Eric-Wasson]

Description

As mentioned in PR #1715: make aggregations only happen when its queried for. When implementing this the frontend has to be changed too, to still include the aggregated data where it's needed.

Another enchancement, but this can be complex since the ORM needs to be changed, is that instead when fieldsets are used, is to not strip them of the object, but specifically only query the database for the fields the user is intrested into. This should be a slight speed up on the database.

Agreed, I created issue #1809 for that
