Bug: 952054
Test: call the `GetProperty` method with a command like this
(substituting a valid device ID):
    dbus-send --print-reply --system \
        --dest=org.chromium.GesturePropertiesService \
        /org/chromium/GesturePropertiesService \
        org.chromium.GesturePropertiesServiceInterface.SetProperty \
        int32:"$DEVICE_ID" string:"Mouse CPI" array:double:500
