Improve UX of sorting in TileUserList

Display alternative (more relevant) user names for specific sorting
modes.

I.e., for "Ordered by: username" option the list now shows usernames,
and for "Ordered by: display name" it shows display names instead. As
for chronological order, the list still uses your "Display preferences"
setting.
