David Zeuthen 869b4c6833 GDBus: Use call() instead of invoke_method()
Lots of people been suggesting this. We still use MethodInvocation /
method_invocation for handling incoming method calls so use call()
instead of invoke_method() helps to separate the client and server
facilities. Which is a good thing(tm).
