Allow adding systems to multiple sets that share the same base set (#7709)

Browse Source 
# Objective

Fixes #7702.

## Solution

- Added an test that ensures that no error is returned if a system or set is inside two different sets that share the same base set.
- Added an check to only return an error if the two base sets are not equal.
