Description

Steps to reproduce:
1. On a 7.0 GA1 bundle, start up Portal and add a Polls portlet to the site page
2. Shut down bundle and export database
3. Upgrade from GA1 to Master using the upgrade tool
4. Start up upgraded bundle and navigate to where the Polls portlet is

Expected results:
1. Polls portlet displays properly
2. Polls can be accessed in site administration
3. A new poll can be added to the portlet

Actual result:
1. Polls portlet is left unconfigured. No console errors are thrown
2. Polls cannot be accessed in site admin (NPE is thrown)
