AA0175 does not mark multiple Finds

Describe the bug When you activate CodeCop with Rule AA0175 all positions where a record is fetched from the database but not used should be found. When you call multiple finds in a row, or with a Reset() inbetween, only the last find is marked as an error.

To Reproduce Steps and to reproduce the behavior:

Create A Function with a local Record Variable (e.g. User)
Enable CodeCop Rule AA0175
Call FindSet(First/Last/...) multiple times
Only the last one is shown as an error

AL Code to reproduce the issue

    procedure AA00175()
    var
        User: Record User;
    begin
        User.FindFirst(); // Should be marked
        User.FindFirst(); // Only this is marked
    end;

    procedure AA00175()
    var
        User: Record User;
    begin
        User.FindFirst(); // Should be marked
        User.Reset();
        User.FindFirst(); // Only this is marked
    end;

In this code no error is thrown, even though the first FindFirst is not necessary

    procedure AA00175()
    var
        User: Record User;
    begin
        User.FindFirst(); // Should be marked
        User.FindFirst();
        Message(User."User Name");
    end;

Expected behavior Every Find Function that is not necessary should be highlighted. It should not matter if you fetch it again later without reading it inbetween.
