Redirect to HTTPS throws exception about http-client

[Danack]

I forgot to say, if you change the request to $request = "https://www.google.com/?q=".$randomWord;, the output is:

Progress::SENDING_REQUEST
Progress::SENDING_REQUEST
Progress::AWAITING_RESPONSE
Progress::READING_UNKNOWN
Progress::COMPLETE

which is weird.

These issues have been addressed in the following commits:

• amphp/artax@d67fa56

This commit improves the error message to help indicate the real problem in this case (a failed socket connection) and provides advice to ease debugging.

• amphp/artax@342aa5f

In the case of the duplicate Progress::SENDING_REQUEST constants the same status was being assigned both when the socket connection was acquired and again when the request was written to the server. This commit adds a new Progress constant, Progress::CONNECTED to differentiate between the two states.
