[BUG] Dialog module sends keep-alive re-INVITES with incorrect SDP

[deeq3]

version: opensips 3.4.10 (x86_64/linux)
Also reproduced on 3.6.x

STR 1

1. Make call with dialog module involved:

create_dialog(Rr);

2. Hold and unhold caller.
3. Wait until re-INVITEs ocurred.
   Expected result:
   Opensips uses last SDP used for caller and callee.
   Actual result:
   Opensips uses last SDP used for caller and last but one for callee.

STR 2

1. Make call with dialog module and rtpengine involved:

create_dialog(Rr);
...
rtpengine_manage($avp(rtp_engine_flags));

2. Hold and unhold caller.
3. Wait until re-INVITEs ocursed.
   Expected result:
   Opensips uses last SDP used for caller and callee.
   Actual result:
   Opensips uses very first SDP used for caller and last but one for callee.
