Is this a regression?
No, this is about standalone components
Description
Consider a simple standalone application with a standalone AppComponent, using a standalone HelloComponent.
On the first ng serve or ng build (or after a ng cache clean), the CLI throws an NG2012 error
🔬 Minimal Reproduction
This is consistently reproducible on this small reproduction: https://github.com/cexbrayat/standalone
npm i
ng serve
It also happens after every ng cache clean followed by ng serve, or when working and adding new components.
Saving the component again usually triggers a new rebuild that removes the issue.
🔥 Exception or Error
Error: src/app/app.component.ts:10:27 - error NG2012: Component imports must be standalone components, directives, pipes, or must be NgModules.
10 imports: [CommonModule, HelloComponent]

Anything else relevant?
This might of course be an issue with the compiler itself, but as the cache is seemingly involved, I thought it was best to open the issue here and let you transfer it.
