Run recently failed tests first during build (OSOE-148)

[Piedone]

A failing test fails the build. When re-running the failed build or changing the code and thus running a new build for the same branch, it would be useful to start test execution with the tests that failed the previous time. Thus, we could get feedback quicker and fail the build quicker if the tests still fail.

This would help us save time (also billable CI time), if the developer doesn’t manage to fix the tests in one go, or if they don’t even work on them at the moment, just keep on committing something else.

This is interesting also for unit tests but mostly for UI tests.
