Fix Memory Leak in AsyncHttpCall affecting auth.listUsers (#2236)

fixes 2235
The socket code was only introduced to fix a bug in NodeJS 12 (db8be26) and since then has even needed a patch (1a34bc4). However the code does not seem necessary at all anymore.
Removing this code resolved the described memory leak.
