Standardize placement of Teams/Communities

On profile pages, the placement of the teams/communities listings varied based on whether the user was logged in or not. This standardizes the location of those listings to the lower-left in the two-column display, which you get when editing your profile, or when viewing the profile of someone with a long statement. When viewing the profile of someone with a short statement or no statement there is a single column and the team/community listings are towards the top.

This fixes #956.
