(closes issue #11849)
Reported by: greyvoip
Tested by: murf

OK, a few days of debugging, a bunch of instrumentation
in chan_sip, main/channel.c, main/pbx.c, etc. and 5 solid 
notebook pages of notes later, I  have made the small
tweek necc. to get the start time right on the second 
CDR when:

  A Calls B
  B answ.
  A hits Xfer button on sip phone,
  A dials C and hits the OK button,
  A hangs up
  C answers ringing phone
  B and C converse
  B and/or C hangs up

But does not harm the scenario where:

  A Calls B
  B answ.
  B hits xfer button on sip phone,
  B dials C and hits the OK button,
  B hangs up
  C answers ringing phone
  A and C converse
  A and/or C hangs up

The difference in start times on the second CDR is because
of a Masquerade on the B channel when the xfer number is 
sent. It ends up replacing the CDR on the B channel with
a duplicate, which ends up getting tossed out. We keep 
a pointer to the first CDR, and update *that* after the
bridge closes. But, only if the CDR has changed.

I hope this change is specific enough not to muck
up any current CDR-based apps. In my defence, I 
assert that the previous information was wrong,
and this change fixes it, and possibly other
similar scenarios.

I wonder if I should be doing the same thing
for the channel, as I did for the peer, but
I can't think of a scenario this might affect.
I leave it, then, as an exersize for the users,
to find the scenario where the chan's CDR 
changes and loses the proper start time.
