Rename refactoring doesn't rename named super formal parameters in subclasses.

[fshcheglov]

In this code

class A {
  A({required int test});
}

class B extends A {
  B({required super.test});
}

class C extends B {
  C({required super.test});
}

Renaming int test in A would rename test in B({required super.test}); but not in C({required super.test});.

I personally encountered this bug when renaming / deprecating APIs in the analyzer.
