CppTools: Fix race condition when opening projects for tests

Browse Source 
The ClangTools plugin tests open a project and immediately trigger a
build afterwards. We checked whether CppModelManager got already data
from the project manager, but this alone was racy for the mentioned use
case as e.g. the QbsProjectManager might still be in parsing mode and
thus the build was not triggerable. Check for the parsing state, too.

While at it, simplify the code by using QTest::qWaitFor(), which also
takes care of posted events.
