[imapsync] patch for 1.267: must log errors when disconnected

[Phil Lobbes <plobbes at zimbra dot com>]

Here's a patch for this bug that I reported a long time ago.  This is short and simple enough that hopefully it will get included.

This patch addresses numerous cases where imapsync might not report an error even if all folder were NOT successfully sync'd because of a dropped network connection.
