[QbsPM] Debug build directory ends with 'Release' suffix

When I open a new QBS project from the QtC, then I see on a "Configure Project" page, that the both build configurations ends with "Release" suffix (I have attached the screenshoot).

It is strange that:

• It does not reproduces with QMake.
• Seems, that QbsBuildConfigurationFactory::availableBuilds() returns a valid infos.
