suzerain: mark working post-0.1.2

On reflecting, I want the version sequence to say 0.1.2.X during post-0.1.2
development and not 0.1.3.X.  This is a one time futzy hiccup on account of the
newish build-ax/version-gen introduced just before 0.1.2.

Revert "suzerain: move to 0.1.3 development"

This reverts commit 9504e9b6969b1a662c6f0679785db989f6f4230e.
