Some panels don't have their name and description set in the "Panel Wizard" section of the administration

Steps to reproduce:

• Hover over "Wiki" and click on "Administer Wiki"
• Click on "Panel Wizard"

There are some panels without a name and description set. I've attached screenshots.

This is the full list of panels without a name set:

• UserWikisIsOwnerWidget
• UserWikisIsUserWidget
• LastCreatedWikisWidget
• MyLastWikiModificationsWidget
• LastWikiModificationsWidget
• UserWikisIsAdminWidget

This is the full list of panels without a description set:

• Applications
• Wikis you own
• Wikis you view
• Last created wikis
• My recent modifications
• Recent modifications
• Wikis you administrate
