http_async_client: do not set global avp lists from t on async callback

- they are done by fake_env() used inside t_continue()
- they were set without reset, living in the process context, resulting
in invalid access when async callback was executed with faked_msg
- related to #2286

(cherry picked from commit 1bc3bbd010705ee247345c1ed9b36210bb8d9ed1)
