Refactoring: "Add Member Function" does not respect 'const'

Using the new refactoring feature "Add Member Function" from QTCREATORBUG-10356.

When writing down a call to a non-existing member function foo() within a const member function bar() of class Foobar the new method added by calling refacotoring:
Add Member Function "foo"
is missing the const specifier:

I get in the private section of class Foobar:

void foo();

but I would need

void foo() const;

So the current refactoring results in a not usable declaration.
