Kent Hansen b8d656d878 Fix autotest gui/widgets dependencies
This is in preparation of removing testlib's
dependency on QtGui and QtWidgets.

Autotests that need QtWidgets api must
explicitly include it (since the types are no
longer provided by the QtGui master header).

Autotests that don't need QtGui or QtWidgets
api shouldn't link against those libraries.
