HMR: change or unlink SFC file not be rendered in time

[HomyeeKing]

⚠️ IMPORTANT ⚠️ Please check the following list before proceeding. If you ignore this issue template, your issue will be directly closed.

• Read the docs.
• Use Vite >=2.0. (1.x is no longer supported)
• If the issue is related to 1.x -> 2.0 upgrade, read the Migration Guide first.

Reproduction

• clone this vite project
• do yarn then yarn dev
• start the project and see a text 111 from Test.vue
• empty the Test.vue
• '111' still on the page , the browser doesn't react for this until you refresh the page
• or delete the Test.vue
• even if refresh the page, the 111 still on page util you perform save (ctrl + s) in App.vue then refresh

I think we should destroy the moduleGraph in watch unlink and let browser fetch the file which import the Test.vue again and at least give some warning in time when .vue file is empty for missing template or render function.
