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.
