plugin XEP-0167: keep media order when starting a call:
media content order is relevant when building Jingle contents/SDP notably for bundling.
This patch fixes the previous behaviour of always using the same order by keeping the
order of the data (i.e. order of original SDP offer). Previous behaviour could lead to
call failure.
