Steps to reproduce

1. Create a project using @vue/cli, select "Nightwatch" in E2E testing
2. Modify the E2E test command to vue-cli-service test: e2e --use-selenium
3. In /node_modules/@vue/cli-plugin-e2e-nightwatch/nightwatch.config.js file, find useSelenium and make a breakpoint for debugging
4. Run yarn run test: e2e

What is expected?

Through breakpoints, although the --use-selenium parameter has been passed on the command line, we can still see that useSelenium return false. The --use-selenium parameter does not take effect and you cannot use Selenium Server.

What is actually happening?

Actually, I have been exploring E2E testing on GitLab CI recently. Unexpectedly found this problem. In the CI environment, Selenium Server is more useful than WebDriver, but it can't be used now

It seems we have a simple typo in the code where we check for the flag's presence.

I submitted a PR.

In the meantime, running tests with --with-selenium should do what you want. But be careful, the next minor might break this as my PR switches this to the correct --use-selenium again.
