Apply to association the same pattern than for attribute (1/2): renamed DefaultAssociation as AbstractAssociation, and implement as SingletonAssociation.

Ensure that the feature is not abstract before to instantiate it, and do not use reflection anymore for some clone implementation.
The reflection was used for cloning a final field. But given that the classes that used them are not so big, the risk of removing
