ProxyBranch.cancel is not sending CANCEL if a PRACK has been used

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a servlet that initiates a Proxy on INVITE and calls Proxy.cancel on 
CANCEL
2. Send the INVITE to the servlet
3. Send a PRACK to the servlet
4. Send a CANCEL to the servlet

What is the expected output? What do you see instead?
The calls to Proxy.cancel/ProxyBranch.cancel is expected to send the CANCEL 
request to the next hop.

But, nothing happens, no exception, no logs.

What version of the product are you using? On what operating system?
3.0.0-SNAPSHOT

Please provide any additional information below.
According to the sources, the logic of ProxyBranch.cancel is explicitly 
verifying that the last request received was an INVITE, which is wrong in the 
case where a PRACK has been used.
