chan_pjsip: also return all codecs on empty re-INVITE for late offers

We should also return all codecs on an re-INVITE without SDP for a
call that used late offer (e.g. no SDP in the initial INVITE, SDP
in the ACK). Bugfix for feature introduced in ASTERISK-30193
(https://issues.asterisk.org/jira/browse/ASTERISK-30193)

Migration from previous gerrit change that was not merged.

(cherry picked from commit 8711c84e3c92ac10a62fc412733419bc2ba82400)
