AsyncClient does not recognize a cert has been passed.

I'm capable of doing the following

$ curl https://foobar.com --cert /path/to/cert

However, when using a Session instance of httpx.AsyncClient, passing the cert gives me error from the server that no certs have been passed.

Closing this. Turns out, if you're using a mix of the transport param with AsyncClient, it prioritizes on the first.
