Cleanup rule 1100 removes base

[matkoch]

Copied from https://youtrack.jetbrains.com/issue/RSPL-6925

When applying code clean up with rule 1100 ticked, in some instances "base" is changed to "this" incorrectly.

We have a class which inherits from List and a new Add(T item) method

We have the last line calling base.Add(T item) which is changed to this.Add(T item)

This causes (caused !!!) us an infinite loop (unit tests missing........)

public class ThingList : List<T>
{
    public void Add(T item)
    {
        ... custom code

        base.Add(item);
    }
}

StyleCop plugin is checking for new or override. I already changed this to compare the called member against the members of the declaring type. Will merge soon.
