The new expression lowering lowers everything after `useValue` / `useFactory` into a separate exported variable. If the value was a `forwardRef`, this was passed to the runtime and resulted in errors. This change unwraps `forwardRef`s during runtime again. Note: we can’t unwrap the `forwardRef` into an exported variable during compile time, as this would defeat the purpose of the `forwardRef` in referring to something that can’t be referred to at this position.
