HTTPSConnectionWithTimeout.connect crashes on Python 3 with debuglevel > 0

The following crashes on a host with no IPv6 connectivity:

Python 3.8.2 (default, Mar 13 2020, 10:14:16)

>>> import httplib2
>>> httplib2.debuglevel = 1
>>> h = httplib2.Http()
>>> h.request("https://api.launchpad.net/")
Traceback (most recent call last):

    sock.connect((self.host, self.port))
OSError: [Errno 101] Network is unreachable

During handling of the above exception, another exception occurred:

    print("connect fail: ({0}, {1})".format((self.host, self.port)))
IndexError: Replacement index 1 out of range for positional args tuple

This is because there's one more layer of parentheses in that str.format call than there should be. The Python 2 version doesn't have the same bug.
