How to reproduce:

• Create a content type that extends 2 content types
• The 2 parents have a view with the same name that is not overriden by the child.
• The child has a merge of the views from its parents => OK
• But the merged view has a wrong order. The order of items in the merged view should reflect the order of the extends declaration in child content type but it doesn't => KO

The issue here is that the super-type array is sorted in a method to get merged view in cache. So the declaration order is not kept.

How to resolve : to find the merged view in cache, use a clone of the super-types array.
