fix #1164.

in nodejs 10, there is a logic in domain.js.

process.on('newListener', (name, listener) => {
  if (name === 'uncaughtException' &&
      listener !== domainUncaughtExceptionClear) {
    // Make sure the first listener for `uncaughtException` always clears
    // the domain stack.
    process.removeListener(name, domainUncaughtExceptionClear);
    process.prependListener(name, domainUncaughtExceptionClear);
  }
});

here listener !== domainUncaughtExceptionClear will crash zone, because listener will be zoneTask.invoke instead of the original listener.

So this PR will just bypass uncaughtException.

also update the travis CI to nodejs 10, to make nodejs 10 work, I updated yarn.lock to update natives to 1.1.3, otherwise gulp will not work. gulpjs/gulp#2162
