I have noticed that the Autoboxing rule works with `IMCFrame` type, and since the `getSecondFrameInMostCommonTrace` was returning a String, I left its signature as it was, then I used the `getTopNFramesInMostCommonTrace` which I made return a List of Frames without formatting.

The formatting was left at the places using `getTopNFramesInMostCommonTrace` if it is needed.
