Fixed bug caused by trying to search for a question by code immediately after it was created.

Objects may not be searchable immediately after they are added to the

Order user questions by creation date (most recent first)
Added question_id url parameter back to /admin request after a new question is created

Done so question control area will be displayed on top of admin page.
JS shows/hides this info based on whether or not question_id url
parameter is present.
Fixed bug caused by trying to search for logged in user immediately after they logged in for first time.
