Rails 5.2 test updates

- Rename test/functional → test/controllers, test/unit → test/models
- Remove test/performance/browsing_test.rb (performance_test_help removed)
- Fix use_transactional_fixtures → use_transactional_tests
- Remove use_instantiated_fixtures (removed in Rails 5)
- Fix ActiveRecord::Fixtures → FixtureSet
- Fix controller test params syntax: add params: {} wrapper throughout
- Fix assert_select targets for aggregator test
- Fix test_update_a_draft_with_changing_the_template: draft → head
- Add test_node.reload after children.create! (awesome_nested_set bug)
- Add before/after count pattern for create tests (transactional isolation)
- Known failures: 5 tests affected by Rails 5 transactional test isolation
