Specifically decreasing the Groove number in a module with no Grooves created throws an unhandled exception. Increasing the number doesn't do anything. I don't recall this occurring in previous versions.

Version: 0.5.2 on wine (dn-famitracker-bin AUR package)

Reproduction steps:

1. In a new module, switch from Speed to Groove mode without creating a new Groove.
2. Decrease the Groove number.
