[webui] Fix tests and update redirect after failed login attempts

* Add test for failed logins.
* Update and rename test for login form.
* Redirect after failed logins instead of using render.
  Since do_login action was called via POST rendering a view here lead to the wrong
  impression that /user/do_login is a valid path for a GET request. Doing a redirect
  prevents this from happening.

Backport 1608

another test case is triggering a build of BaseDistro3 package.
ensure that the submitted build result matches with current sources
