Implement Apollo cache in a more understandable for newcomers way

[KristianWEB]

Is your feature request related to a problem? Please describe.
As you already know we are utilizing Apollo Cache for our local state management. The problem is the way we store/retrieve data is kinda weird and magical so we are gonna make that process easier by implementing some custom methods that are redux likely and more people will understand whats going on.

Describe the solution you'd like
Use this article and Apollo docs to refactor our current apollo cache setup into something more understandable.

You can work on this feature by creating and using a branch called feature/refactor-local-state

Pull Request Squashing

Please, go through these steps before you submit a PR.

1. Make sure that your PR is not a duplicate.
2. If not, then make sure that:

2.1. You have done your changes in a separate branch. Branches MUST have descriptive names that start with either the fix/ or feature/ prefixes. Good examples are: fix/signin-issue or feature/issue-templates.

2.2. You have a descriptive commit message with a short title (first line).

2.3. You have only one commit (if not, squash them into one commit).

2.4. npm test doesn't throw any error. If it does, fix them first and amend your commit (git commit --amend).

3. After these steps, you're ready to open a pull request.

3.1. Give a descriptive title to your PR.

3.2. Provide a description of your changes.

3.3. Put closes #XXXX in your comment to auto-close the issue that your PR fixes (if such).
