Title: Convert plugin class set into a list before indexing into it

The beets plugin module was changed (https://github.com/sampsyo/beets/commit/e2718d792e814248fc336d13a6c5c33e4b579277) to store the plugin classes in a set rather than a list. This pull request updates the supporting test code to accommodate this change.
