Add an option to mark the last/interrupted test as passed when resuming a session

[Sylvain Pineau]

One can mark the previous test as failed or rerun it when resuming a session. But there's no way to say that the test was successfully run. A perfect example is the reboot test.

Actual result: No Gui element to mark the previous test as passed

Expected behaviour: A new option on the resume screen to choose if the previous test is passed or not.

For the record,
I think we're able to mark poweroff / reboot tests as "Passed" after selecting the "rerun" option.

But it will be great to have an extra "mark the last $name test as pass / faill and continue" option available.
