Since Rails 5 request.format gets set by extension if it's not explicitly
set.
That means artifacts_controller#file no longer works as expected.
This commit explicitly sets request.format for artifacts_controller#file.

Refactor sessions_controller_spec to work both in rails4 and rails5.
Remove the stubbed `request.referer` method, set real header instead.

In Rails 5.0 there's a bug [1] in controller tests that doesn't parse
nested parameters correctly.

This commit brings a workaround to make specs work again both in rails4
and rails5.
