Version

3.2.1

Reproduction link

https://github.com/bodograumann/vue-cli-generator-api-entry-file-bug.git

Node and OS info

Node v8.12.0 / npm 6.4.1 / Linux 4.17.19-gentoo

Steps to reproduce

git clone https://github.com/bodograumann/vue-cli-generator-api-entry-file-bug.git
vue create --preset ./vue-cli-generator-api-entry-file-bug test

What is expected?

The output contains GeneratorAPI.entryFile before and after @vue/cli-plugin-typescript is installed. First that is src/main.js and later src/main.ts. So it should say:

🚀  Invoking generators...
src/main.js

What is actually happening?

Both times src/main.js is returned, because the first value is cached. If the first call to GeneratorAPI.entryFile is removed though, the remaining call will return the correct value src/main.ts.
