Stubbing ApplicationSetting.current in stub_application_setting
What does this MR do?
At the moment we're not consistent about how we're accessing ApplicationSetting. In the test suite, we have stub_application_setting to stub the settings, but we don't cover the ApplicationSetting.current. This MR stub also that case.
It refactors as well some old stubbing references in the specs like allow_any_instance_of(ApplicationSetting)... to use the stub_application_setting method.
Does this MR meet the acceptance criteria?
