When Turbolinks is enabled, a `redirect_to` in a `format: :js` request
will emit code that instructs Turbolinks to navigate to the page.
Turbolinks will then load the redirection target as HTML, and display
it.
But with Turbolinks disabled, the same `redirect_to` will instead
respond with a standard `302: redirect`. `Rails.ajax` will interpret
this redirect as "Please perform the same call again to the redirected
URL, in the same format" – and request our redirection target, but
using `format: :js`.
This breaks the "Publish procedure" button. In that case, we really want
the page to be navigated to. Add an explicit JS redirect, so that the
redirection occurs in HTML.
When cliking on the "Delete attachment" link, and opening the URL
in a new tab, the `DELETE /attachements/:id` will become
`GET /attachments/:id` – which will cause the `show` action to be
routed with an html format (instead of JS).
In that case, we don't want to throw an error at the user face.
Instead simply re-render the dossier page (if any).
Fix a long-standing error in Sentry.
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.

Turns out that assigning the params to the procedure calls `read` on the
images files. Calling `read` moves the seek offset to the end of the
file; which means that subsequent calls to `read` return an empty
string.
Fix the issue by calling `rewind` before attempting to `read` the file,
to ensure the seek offset is at the beginning of the file.
