getAllMethodNames does not differentiate between overloaded methods

[markgoho]

Describe the bug
When finding the methods within a class, overloaded method signatures are ignored.

To Reproduce
Steps to reproduce the behavior:

Create a class with a method that has multiple signatures with the same name (called function overloading).

Try to create an auto-spy from that class and spy on that method. There is no way to specify which overload is to be mocked/spied on.

Expected behavior
Among the overloaded signatures, one is able to be selected or specified.
