ID 469529 - When you add a Constant item via Python the Color option is missing.

Problem summary

When you add a Constant item via Python the Color option is missing.

This is due to the Constant item not having the Diffuse Color effect applied to the Constant item. When you create a Constant item via the Add Layer option in the Shader Tree this effect is applied to it by default on creation.

import modo
s = modo.Scene()
s.addItem("constant")
3) Go to the created Constant item inside of the Shader Tree and notice that the Color option is missing.

Expected behaviour

Creating a Constant item through Python or GUI should result in the same result.

Actual behaviour
Creating a Constant item via Python results in the Color option not being present.

Workaround
Set the Effect to Diffuse Color.
