feat: create projects with @vue/test-utils beta 31 (#5147)

See changelog at https://github.com/vuejs/vue-test-utils/blob/v1.0.0-beta.31/CHANGELOG.md#100-beta31-2020-01-18

New projects will be created with this new version.

There are a few breaking changes since beta.29. So we can't automatically migrate existing projects to this new version. Users can upgrade at their own will.
