  manager: Make challenge work with allowmultiplelogin=no
  
  Prior to this patch, challenge would yield a multiple logins error if used
  without providing the username (which isn't really supposed to be an argument
  to challenge) if allowmultiplelogin was set to no because allowmultiplelogin
  finds a user with a zero length login name. This check is simply disabled for
  the challenge action when the username is empty by this patch.
