Refactor vuex store

[jappe999]

Expected Behavior

I want to use dictionaries in the state and transform them to arrays when needed. This is better, because I can easier filter duplicates, fetch single entities and update or delete them.

Current Behavior

Right now everything is done in arrays. Because of this, I need to perform a lot of mapping and filtering.

Possible Solution

Use dictionaries instead of arrays in the state. Transform those dictionaries to arrays when needed in the getters.

Context

The code is getting a little more unreadable every time I use an array method in the store.
