[reSIProcate] ClientAuthDecorator is deleted after its creation

[Dmytro Bogovych]

Greetings.

I migrate client VoIP toolkit to new 1.7 version. I made simple test
with registration.
I discovered that now client authentication is handled through
ClientAuthDecorator. Cool.
There is a call stack for decorator creation point on response message.

ClientAuthDecorator instance is add to message object. Good.

BUT the next line in DialogUsageManager::send(), line 866 clears
message decorators.
Of course client is not authenticated by server.

Is it my bug or resiprocate's one?

Thank you :)
