[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.
