[App Components] Fix flow for components

[loui981c]

Description

Fixing the order and functionality of the flow between components.

Changes

Fetching the different section components in the same order as the content-creator has created them. It is impossible to go to the next slide if the slide is an exercise and the user has not answered the exercise. When the user stands on the last slide, the continue button navigates to completeSection.

Notes for Reviewers

The last section 'Section with lectures and exercises' of the course 'Financais Pessoais' should work since it is the only section with the new structure in DB
