[kde-freebsd] area51's sysutils/nepomuk-core fails with clang

[Schaich Alonso]

Reproducable on RELEASE-9.1, STABLE-9 with CLANG_IS_CC and CURRENT, all recent 
versions.
It can be fixed by adding the parantheses as proposed by clang in the first 
analysis output, and all others are followup errors.
While I still don't know why that is needed, it still is required for 
clang-3.2. Of cause, removing the compilation of querytests from the 
CMakeLists.txt also fixes the issue.
