Remove JSC.Strong from NodeHTTPResponse

[Jarred-Sumner]

What does this PR do?

Remove the JSC.Strong for the Promise from NodeHTTPResponse. This means that the only strong reference to the NodeHTTPResponse object comes from the socket.

Note that this won't impact promise rejections because those are kept as strong inside the JSGlobalObject.

How did you verify your code works?
