unittests: explicit stringify StringRefs for conversion

When clang is built outside of the LLVM tree (against a corresponding version),
there is no definition providing for operator<<(std::ostream &, StringRef) which
is required for the assertion routines in google-test tests.  Avoid the
compilation failure by explicitly stringifying the StringRef prior to use.
