Bump ejs, @vue/cli-plugin-e2e-cypress, @vue/cli-plugin-unit-jest and …

…@vue/cli-service (#487)

Removes [ejs](https://github.com/mde/ejs). It's no longer used after updating ancestor dependencies [ejs](https://github.com/mde/ejs), [@vue/cli-plugin-e2e-cypress](https://github.com/vuejs/vue-cli/tree/HEAD/packages/@vue/cli-plugin-e2e-cypress), [@vue/cli-plugin-unit-jest](https://github.com/vuejs/vue-cli/tree/HEAD/packages/@vue/cli-plugin-unit-jest) and [@vue/cli-service](https://github.com/vuejs/vue-cli/tree/HEAD/packages/@vue/cli-service). These dependencies need to be updated together.
