Migrations: -1 version goes to 0, not current version minus 1

If you migrate with /version -1, it migrates down, but all the way down
taking -1 as a literal for call down all the way to 0.

I added functionality so that if you pass in -1, it moves to current issue
minus 1. This is implemented as a literal look, so if you do -2, you get
the previous behavior. Also if you want to move to 0, you should explicitly
pass 0.

Patch attached.
