Autotests not run from install-root

When using the AutotestRunner item, the command qbs build -p autotest-runner cause execution of the unit tests in their build directory.
It would be nice if the tests were executed in the install root directory instead.

The command qbs run -p autotest-runner returns this weird result:

ERROR: Cannot run: Product 'autotest-runner' is not an application.

Basically, depedencies and test suites are built, then run from their build directory, then executed but qbs finally fails.

Notes:

• My use case is that some of my unit tests requires the project to be fully installed (need to access data and config files from their "well-known" locations)
• Althought, Qbs and QtCreator don't depend on each other, there's an inconsistency. QtC run any 'runnable' (CTRL-R) from their install dir.
