gitadora: fix order of drums in Buttons tab (#531)

## Link to GitHub Issue, if one exists
n/a

## Description of change
Before this PR, drums were in the order they appear in test menu.

This is really confusing. Change it so that they appear in the order
they do in default drummania layout.

## Testing
validated manually in gw
