Revert the outer module object to an object (#26093)

This is because Webpack has a `typeof ... === 'object'` before its esm
compat test.

This is unfortunate because it means we can't have a nice error in CJS
when someone does this:

```
const fn = require('client-fn');
fn();
```

I also fixed some checks in the validator that read off the client ref.
It shouldn't do those checks against a client ref, since those now
throw.
