Fix bug 60471 by correctly identifying unused speculative preconnections

* Correctly identify unused speculative preconnections from browsers
  like Chrome and Firefox
* Add a new message to the debug level that is emitted when a TCP
  connection is closed without sending any request (a preconnection)
* Fix an issue where the existing debug messages were not being
  displayed even when debug mode was enabled
