fix(listener): Limit retries to a maximum of three.

fixes #266

If the application did not include Transfer-Encoding: chunked, depending on the timing of enqueue, it would loop indefinitely until the second chunk was read.

One way to do this is to treat text/event-stream as special, as @yusukebe pointed out in this comment, but I would prefer to resolve this without depending on a specific Content-Type.

#265 (comment)

Essentially, the problem was simply #265's i-- and currentReadPromise = reader.read(), so I think that fixing that should be sufficient without any additional logical changes.

Hi @usualoma

I've tried some edge cases based on your repro. They work well! Looks good, thank you!
