Test helpers are separated between two files: spec_helper and
rails_helper. This separation is meant to allow tests that do not
require Rails (like testing standalone libs) to boot faster.
The spec_helper file is always loaded, through `--require spec_helper`
in the `.rspec` config file. When needed, the rails_helper file is
expected to be required manually.
This is fine, but:
- Many test files have a redundant `require 'spec_helper'` line;
- Many test files should require `rails_helper`, but don't.
Not requiring `rails_helper` will cause the Rails-concerned section of
the test environment not to be configured–which may cause subtle bugs
(like the test database not being properly initialized).
Moreover, Spring loads all the Rails files on preloading anyway. So the
gains from using only `spec_helper` are thin.
To streamline this process, this commit:
- Configures `.rspec` to require `rails_helper` by default;
- Remove all manual requires to spec_helper or rails_helper.

The instructeur, dossier and claimant where created regardless of
wether they already existed or not.
With this commit:
- Associations are declarated in a more idiomatic way
- They are correctly not created if they are provided when creating the
object.
Now that all states have a dropdown, we can simplify the code.
This also brings the "Repasser en instruction" action for all states
(including when no attestation or motivation is present).
- Fix the missing link to see attestations (see #4400)
- Fix the "Repasser en instruction" wording being confusing for
accepted state
- Add lot of tests
