Pcm2Java reactions: Rename Operation Required Role fails to remove old assignment in constructor

[h4uges]

An OperationRequiredRole in Pcm creates, among other things, an assignment statement in the constructor of the associated component. When renaming an OperationRequiredRole, the old statement is not removed but a new assignment statement is added. The same behavior probably also occurs on other changes to OperationRequiredRole.

public class TestBasicComponentImpl {
	public TestBasicComponentImpl(testRepository.contracts.TestInterface newName) {
		this.oldName = oldName; // not removed assignment
		this.newName = newName;
	}
	private testRepository.contracts.TestInterface newName;
}

To fix this the correspondence model of OperationRequiredRoles has to be changed. Currently, a part of the correspondences is not resolved via the correspondence model but via the entity name.

#243 adds a unit test which tests this behavior, that is currently disabled (OperationRequiredRoleMappingTransformationTest.testChangeOfOperationRequiredRole)
