[REG] No completion for QCOMPARE and QVERIFY in auto test project

• Create a new Auto Test project, keeping all defaults
• Build and run the project, the editor should now be code model warning free
• Try to add QCOMPARE or QVERIFY in a test case, there is no completion offered

After the first QCOMPARE or QVERIFY is in the project, adding furthers triggers the completion

I just noticed, that in the simple test case the completion never triggers. So it looks like a regression to me.

Note that this is the official beta2 release with Clang Code Model active.

It seems to work if I include <qtestcase.h> direcly. However, including <QtTest> (which also includes <qtestcase.h>) is not enough.
