Make most of the Vuex store modules namespaced

Description

This PR moves most of the Vuex store modules from store-modules to store directory. This way, Nuxt creates namespaced modules out of them, which are easier to maintain.

Technical details

To make the transition to namespaced modules more atomic, one large #229 is replaced with #242 and this PR. Also, the filter-store and search-store are left as is because they are tightly coupled, and will be refactored in a later PR.
There are two things that needed to be changed in every store module:

• namespaced modules require state to be a function that returns the state object, instead of an object
• namespaced modules require actions to be plain object, so to pass data fetcher services into actions, createAction functions were added. This makes it possible to switch services with mocks when testing.

Tests

Run the tests, and run the app to verify that no error messages appear in the console.

Excellent. Tests pass and everything is working. I went through a little manual integration test suite haha, and everything works as it should. What a large amount of work!

What's the difference between this PR and #229?

[sarayourfriend]

Just a curiosity, but why were these not using mapState before?

[obulat]

I am not sure, probably because that was the understanding at the time of writing of this code.

Oh sorry, I should have read the description more closely. Never mind!

Looks good to me! Code changes make sense and it tested well locally. Nice refactor!
