I was installing freeipa-server earlier today and it failed with Unable
to guess signature from empty list.
I was unable to reproduce it but there is now harm in explicitly
specifying the signature of the empty list to prevent this issue.

Subject: [PATCH] dbus: Create empty dbus.Array with specified signature
Python DBus binding could fail to guess the type signature from empty list.
This issue was seen but we don't have a reproducer. There is no harm in making
sure that it will not happen.
