LPS-38097 - When editing a page of type "panel", the list of applications does not reflect the apps previously added

Hey @Robert-Frampton,

Attached is an update for http://issues.liferay.com/browse/LPS-38097.  Can you look at why the applications treeview is missing from the control panel?  I've also added a source formatting commit so you can squash it all together and resend me when it is complete.

Please let me know if you have any questions.  Thanks!
