No need to init mojo edk any more, content::UnitTestTestSuite constructor will
do this. #When constructing content::TestBlinkWebUnitTestSupport

   base::TestIOThread test_io_thread(base::TestIOThread::kAutoStart);
   std::unique_ptr<mojo::edk::test::ScopedIPCSupport> ipc_support;
   ipc_support.reset(
       new mojo::edk::test::ScopedIPCSupport(test_io_thread.task_runner()));
 
   return base::LaunchUnitTests(
       argc, argv, base::Bind(&content::UnitTestTestSuite::Run,
                              base::Unretained(&test_suite)));
 }
