fix: Use new stream rather than pipe

[thebrianchen]

Fixes #661.

We use a single long-lived stream for all of our logic. If the backend streams drops, we unpipe the old stream and pipe and new stream. After many re-connects, it seems to cause EventEmitter leaks (#661). By using new streams rather than piping/unpiping a long-lived stream, the MaxListenersExceededWarning should no longer appear.

Thanks! Since this is a seemingly unrelated fix to #661, can you explain what you are doing in the PR description?

I think we may have now earned a Moma badge by moving this TODO around more than 10 times :)
