Find usages and renaming for constructor fields

I've been trying to make this work. However, there are some problems with the custom ConstructorParametersReferencesSearcher that I've implemented. Find usages works properly. However, that causes some other problems:

• When I rename the constructor parameter in the constructor method then my element in the annotation is not renamed. This is tested by MapstructMethodUsagesSearcherTest.testRenameConstructorTargetReferenceMethod
• When I rename the element in the annotation and the class is in the same file as my annotation there is an error happening. This is tested in RenameHandlerTest.testRenameConstructorTargetParameter. When I run the plugin in an IDE and the class is not in the same file as my annotation then the renaming is correct.

Empieza con el ConstructorParametersReferencesSearcher personalizado y las dos pruebas mencionadas: MapstructMethodUsagesSearcherTest.testRenameConstructorTargetReferenceMethod y RenameHandlerTest.testRenameConstructorTargetParameter. Reproduce ambos escenarios de renombrado de parámetros del constructor e inspecciona sus fallos. La tarea está terminada cuando ambas pruebas pasan, incluido el renombrado de un elemento de anotación cuando la clase está en el mismo archivo, sin errores.
