Rename method of generic type misses one method

[stephan]

Tests #testGenerics1 and #testGeneric3 in org.eclipse.jdt.ui.tests.refactoring.RenameVirtualMethodInClassTests fail to rename one method reference.
See:

• http://www.objectteams.org/distrib/jacks/1.1.6/junit/tests/test-d3e66688-testGenerics1.html
• http://www.objectteams.org/distrib/jacks/1.1.6/junit/tests/test-d3e66696-testGenerics3.html

These refactorings require the RippleMethodFinder2 which has not yet been integrated with the OT/J (needs RegionBasedOTHierarchy).

Disabling these two tests for now.
