Problem

If we define a component used by App.vue with a prop typed as:

props: {
  user: Object as PropType<UserModel>,
},

then VTI (0.0.15) throws:

File : /Users/ced-pro/Code/test/vue-cli-tests/template-typechecking/src/App.vue
Error: Cannot find name 'UserModel'.

Reproducible Case

This is reproducible in a bare CLI project with TS enabled:

npx @vue/cli@ create vue-integration -m yarn --inlinePreset '{"useConfigFiles": true,"plugins": {"@vue/cli-plugin-typescript": {"classComponent": false},"vue-cli-plugin-vue-next": {}}}'

In the generated project, update HelloWorld.vue to have a user prop as above, then run vti in the project.

You can check out cexbrayat/template-typechecking#1 and run yarn vti for a quicker repro.
