Fix rules that were applied even if no actual change was made

[carlos-granados]

In all three cases, the problem existed because some functions did not actually change nodes in a way that would result in a code change, they just added attributes to inner statements or expressions so that other functions could work on the code, but they still returned a node value as though it had been changed. I modified this so that these functions did not return a node. I also changed their name as they were called refactorXXX and no refactor was actually done in these functions, so I used what I think are more appropriate names
