[views] remove breadcrumbs usage to retrieve last visited page Use JavaScript history.back to go to the last visited page. Rename _return_to_lastpage to _redirect as it becomes misnamed. Drop `test_redirect_default` test in `unittest_views_basecontrollers` which essentially tested this (now removed) breadcrumbs "feature". Closes #5456850.
