Avo installer: PostTypeFilter passes a record where by_post_type expects a name

[kanejamison]

Problem

On branch set-up-an-avo-installer-rake, lib/tasks/templates/avo/filters/post_type_filter.rb.tt:

post_type = PostType.find_by(name: value)
return query if post_type.nil?
query.by_post_type(post_type)

by_post_type (lib/bunko/models/post_methods.rb:36) filters by post_types: {name: type_name} — passing a record means the filter silently matches nothing.

Proposed solution

Use query.where(post_type: post_type) (or pass post_type.name).

Acceptance criteria

• Selecting a post type in the Avo filter actually filters the index (test in test/tasks/bunko_avo_task_test.rb or an integration test).
