The required rights analysis doesn't consider TextAreas with default content type

Steps to reproduce:

1. Login as a user without script or programming right
2. Create a class with a "TextArea" property.
3. Create a page with an object of the class and in the content of the property, use a Velocity macro.
4. As admin, try editing the page with the object.

Expected result:

A warning is displayed about the Velocity macro.

Actual result:

No warning is displayed.

Note that this issue only reproduces when the content type is the default value. If "Wiki Syntax" is explicitly selected, the analysis works as expected.
