Fixed a regression that prevented a flow with multiple paths to display properly
Removed unwanted change to flow, remove a debug code left behind and replace composerList.splice(0, composerListLength); by composerList.length = 0; to avoid creating an unnecessary array
Added a test to track a regression that happened in collections/listen/property-changes.js
Merge pull request #1508 from marchant/collection-listen-fix-test
