_stream_wrap: prevent use after free in TLS

Queued write requests should be invoked on handle close, otherwise the
"consumer" might be already destroyed when the write callbacks of the
"consumed" handle will be invoked. Same applies to the shutdown
requests.

Make sure to "move" away socket from server to not break the
`connections` counter in `net.js`. Otherwise it might not call `close`
callback, or call it too early.
