Fix client component imports are not being correctly tracked

[shuding]

When there're multi-level server component imports, some components are eliminated after going through the client compilation, because we are only tracking .client. dependencies inside .server. components. Instead we should keep all imports for the client compilation, but only remove the content of server components.

This fixes vercel/next-react-server-components#7.
