Subject: Better cache names for accessory-formula

Because formula don't get named unless the brew kit instantiates them accessory formula were getting named "__UNKNOWN__". Which sucks.

This isn't ideal for me as I made the naming use @name and @version to ensure unique naming. Now it is possible to have name clashes in the cache. So I need to solve it better at some point.---
