Recording completion callback after on_end

[system123]

The call recording completion callback is fired after the call on_end handler. This is a problem as it means the call on_end handler cannot perform operations on the recording URL as it is only returned after the on_end handler.

Issue was described here: https://groups.google.com/forum/#!topic/adhearsion/jhIj4UPkgM0

Code which should be able to recreate the issue is here:

I suspect this example might be minimised to eliminate the second call, replacing it with a sleep.

Additionally, I would appreciate full TRACE level logs of such a reproduction.

I have updated the Gist to include a TRACE log, I also updated my example to one which reproduces the problem. Removing the second call and using sleep instead as well as moving the start recording out of the on_joined callback did not produce the issue. It seems it is only reproduced in when setup with a second call.
