[dbus] Handle D-Bus name owner handoff correctly. JB#46305

Name ownership transfers from one owner to another are not handled
correctly - which can cause problems in cases where such ownership
handoffs are desirable e.g. switching from unlock agent to lipstick
during home unlocking operation.

Treat name owner handoff internally within mce as name owner lost
immediately followed by name owner gained.
