There was a fix for QTCREATORBUG-7730 in the case of nested
forward declarations in commit 74a458bca0.
However, it introduced regressions and actually didn't solve
the issue, since the behavior was hidden by another error fixed later.
The patch should properly fix the issue and the regression pointed
in QTCREATORBUG-7777.
