ChangeLog: Update info from last merge

Add info about being in sync with pip-tools 1.10.1.

Note: There were no new bug fixes or features, since the TypeError
failure in sync on Python 3 was already fixed in Prequ 1.0.0 and the "Do
not allow conflicting pinned versions" fix was released in Prequ 1.0.2.
