change task name, use `.build`
change task name, use `.build`

- make `choose` task more explicitly named (if this generator is used as a plugin, and the "consuming" generator also has a `choose` task, it would overwrite the `choose` task on this generator)
- use `.build` instead of generate, since all of the tasks are on the current generator. Also, `.generate('default:...')` would run the "default" generator. Which is the `generator.js` in the user's current working directory. So that would only work when the generator is in your cwd (which makes sense why it would work when you're developing)
