This CL fixes the following issues: * The Travis CI had the ctest invocation followed by a ";", so non-zero exit codes (indicating test failures) did not cause the build to fail. * The AppVeyor CI had the ctest invocation followed by a ";", causing an error on Windows, where "&" plays the role of ";" [1]. The Windows CI (AppVeyor) will still be red after this CL, as some of the tests are failing. However, this CL is a step forward, as it gets us from failing to start tests to running tests and recording success/error states.
