Crash in nm-pptp-service.c

[Eivind Naess <eivnaes yahoo com>]

All, 
Looks like I ran into a crash with nm-pptp-service.c in latest git-head. The 
call to strlen() did in my case cause a crash when priv->domain is set to NULL. 
Simple patch as below checks for value of priv->domain before passing it to 
strlen()..
