Bug: 952054
Test: call the `GetProperty` method with this command (substituting a
valid device ID):
    dbus-send --print-reply --system \
	--dest=org.chromium.GesturePropertiesService \
	/org/chromium/GesturePropertiesService \
	org.chromium.GesturePropertiesServiceInterface.GetProperty \
	int32:"$DEVICE_ID" string:"Log Path"
