WL-3621 : helpdesk pages shouldnt have dropdown list of maintainers or site contact listed


Couple of changes:
1.   For just the Technical Report, they should not have the drop down list and should not list the site contact so I've deleted these.
2.   For just the Technical Report, the email should always go to the weblearn email.
So in FeedbackEntityProvider.java, I've got some common logic for where the email should go for both reports.

Ps. The indentation for this file is inconsistent
