http: fix double AbortSignal registration
It looks like https://github.com/nodejs/node/pull/36431 added support for AbortSignal to net.createConnection
and net.connect
(will add tests/docs in a separate PR). This caused "double registration" to the AbortSignal. This PR fixes the issue by removing the signal from the internal calls to net
.
Also added tests for http.agent
