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.

Inizia con il ConstructorParametersReferencesSearcher personalizzato e i due test indicati: MapstructMethodUsagesSearcherTest.testRenameConstructorTargetReferenceMethod e RenameHandlerTest.testRenameConstructorTargetParameter. Riproduci entrambi gli scenari di rinomina dei parametri del costruttore e analizzane i fallimenti. L'attività è completata quando entrambi i test superano, inclusa la rinomina di un elemento di annotazione quando la classe si trova nello stesso file, senza errori.
