The function that was checking if the job was started or not
was expecting a boolean, however it was receiving a null.
During the refactor the condition was changed, causing the function
to break with null

This commit fixes the check

This commit adds back `js-` classes needed to
automatically collapse the sidebar on resize.

When the job page is rendered we fetch the pipeline
endpoint to render the stages in the sidebar.
Without `.json` the response is cached, and when the
user goes back to the pipeline's page it renders the
json output instead of the Vue app

In the refactor the `!` reference was missed
This commit adds it back and adds coverage for it.

Removes old mediator and service pattern and uses the new store.
Middle step before moving everything into one single vue app

The eslint-plugin-vue upgrade had some breaking changes to
vue/attribute-order which needed to be resolved in order to avoid
disabling the rule entirely

Rename btn-new, btn-create and btn-save to btn-success
