Linting and specs

[HHassig]

This should be a much cleaner and organized version of the other branch. I left the other branch for reference, can be deleted.
Only think (i believe) left to do is "Lint ruby files" https://github.com/Platoniq/decidim-b4m/commit/6fbc9c165a2160deef5d2cf59e3de30f1ca9d1e7

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

Please, run: bundle exec rubocop -A to autocorrect all the files with rubocop and check with bundle exec rubocop -P if you need to correct something manually and do it too.

There is an error in the test CI. Please check it too. It seems the repo doesn't have a schema.rb file
