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.

Capybara logs several warnings during tests:
> Locator Integer:243 for selector :link must be an instance of String
> or Symbol. This will raise an error in a future version of Capybara.
This is because we use selectors like `have_link(dossier.id)`, where the
locator is a Number (instead of a String or Symbol).
Displaying separate estimations for en_construction and en_instruction
doesn't really make sense for the users: they want to know how
long it is going to take overall, not the petty details of our workflow.
