Before this commit, the makeView test helper processed the given
arch and generated the fields to pass to the View component. This
led us to do a similar work as what is done in the view service,
i.e. duplicate code, or factorize/reuse code.
An alternative is to let the View component fetch whatever it needs
(view arch, fields, search view...). This is the purpose of this
commit. That way, the code of the view service is executed (and
thus tested as well) in each test doing a "makeView".
This commit makes that change, and adapts some tests accordingly
(mainly, tests doing assertions in mockRPC, since we do a get_view
in every test).
