New Revision: 239427

Log:
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)
