_scheduler: Fix dont display a failure for terminated jobs

See merge request !1096

This test has one test case which is marked as an integration test,
and the other is not an integration test, but was using the integration
cli. The integration cli does not work correctly if not run in
integration mode.

This was causing an error locally in conftest.py when trying to
create a tmpdir inside a nonexisting integration cache directory.

tests/integration/pullbuildtrees.py: Fix the non-integration case.
