KIM_Tests silently fail

When running KIM_Test on current master, the result is

[==========] Running 2 tests from 1 test suite.
[----------] Global test environment set-up.
[----------] 2 tests from KIM_Test
[ RUN      ] KIM_Test.feature_can_do_10_iterations
Model Object Created
Unrecognized lattice structure. Use BCC, FCC, HCP, Diamond or SimpleCubic. Exiting...

This is an error but still considered as success by the CI because of an exit(0):

      std::cout
          << "Unrecognized lattice structure. Use BCC, FCC, HCP, Diamond or "
             "SimpleCubic. Exiting..."
          << std::endl;
      exit(0);
