Asterisk does not support multiple elements in Accept header for MWI SUBSCRIBE.

This patch fixes it.

I'm doing some cleanup on the tracker.

Do you want to push this through the review process for recent supported versions of Asterisk?

If not, then we should close this out as it hasn't seen any traction since 2012 and chan_sip is now under extended support so it likely won't be moving in anytime soon.
