Summary:                    [patch] Hang up during call forward into voicemail
crashes Asterisk.
Description: 

I've discovered an always recreatable crash:
Here is the call secenario:

1) set number1 to call forward all to number2
2) call number1 from number2
3) "End Call" quickly: number2 starts to rings itself.
4) Press "Reject" to send call to voicemail.

At this point the call is sent to Asterisk and Asterisk starts
VoiceMail(number2) although the phone has already hung up.

The crash is in the expunge process where the IMAP stream is actually NULL
at this point.  

This patch checks for a NULL mailstream before expunging messages.
