[UbuntuShape] Fixed deprecation logging issues.
This fix prevents logging a deprecation warning for "image", "color" and "gradientColor" properties when the import version is less than 1.3. The logging of properties used internally (through the old image wrapper) have been removed too since the user might not even have used them. Fixes: https://bugs.launchpad.net/bugs/1519414.
