Add the job/session name of the repository to Saucelabs tests

I know this is a simple config change but if you're going to run 20+ repositories under the same Saucelabs account you need an easy way to identify the jobs in Saucelabs reports

It'll display the session name as `delite` rather than `tests/intern` (so you can identify more easily deliteful, liaison, gfx etc etc tests).
for info: there's a tags array property you can add too but I don't see the use for it
