Tweak gitlab yaml to ensure failures always reported

Tweak gitlab yaml to ensure failures always reported.

Essentially require the exit 1 to be the last command possibly executed in order for the test to be correctly detected as a failure. Probably also possible to use something like set -x to avoid this issue. Intend to refactor this more inline with the approach for travis soon, but good to get the tests reporting currently asap so the CI is useful.
