Viewpoints should only be fetched once

[maxime-huyghe]

Description

Currently, due to a quick fix, viewpoints are fetched both in PillListViewpoint and Viewpoint.

What is the valuable outcome that cannot be achieved because of this bug?

• Fast loading in every case
• Saving network bandwidth and server load.

For which stakeholder (people, role, project, domain) is it important?

Reproduction scenario

1. Load an item

Expected behavior

Viewpoints are only loaded once.

Environment

• OS: any
• Browser: any

Workaround

Factorize the loading to the Item component. This is harder than it looks because the data is strangely shaped.

Deliverables status

Phase 1

• Scenarios (Gherkin) (not needed)
• Implementation strategy

Phase 2

• Acceptance tests (Capybara) (not testable)
• Implementation
