  fixes text support in sdp answer

  The code that handled setting 'm=text' in the sdp was not executing
  in the correct order.  The check to see if text was needed came after
  the check to add 'm=text' to the sdp, this resulted in 'm=text' always
  being set to 0 because it looked like text was never required.

  (closes issue #16457)
