wrong total number of tests and failures reported

[Didier Roche-Tolomelli]

Daily release view doesn't report the right number of tests which are actually run and failures:
- for instance, the apps are passing 100% though to be able to publish:
https://jenkins.qa.ubuntu.com/view/cu2d/view/Head/view/Apps/job/cu2d-apps-head-2.2check/125/ (last time tests run because we had something to publish in the apps stack), triggering:
https://jenkins.qa.ubuntu.com/job/autopilot-saucy-daily_release/557/ (164 tests, all passing)
The dashboard mention a total of 160 tests, and 28 of those failing. Not sure where those numbers come from :)

- the phone stack seems from the dashboard to have no tests running, where some runs:
https://jenkins.qa.ubuntu.com/view/cu2d/view/Head/view/Phone/job/cu2d-phone-head-2.2check/17/ (2 tests in fact, but still >0). Same for friends, media, mirslave…
