The effectif_mensuel was a number, it needs to be converted explicitely
into a string.
As a bonus, `nil.to_s` is `""`, so we can remove the special case for
nil.
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.

- as a user, it should not display the administration info
- as an instructeur, it should display the administration info
- it should render the proper view with no crash
When attempting an invalid transition on a dossier, provide a meaningful
error message (instead of letting an `AASM::InvalidTransition` exception
propagate).
This handles not only the case where the same state is applied twice
(which was already handled manually), but all cases where the transition
is invalid.
It was slightly broken in two ways:
- it doesn’t make other instructeurs unfollow the dossier
- if the dossier is unarchived, instructeurs don’t refollow automatically.
