Refactors should not reformat the code

[jordanmontt]

Currently, several refactors reformat the code when applying a refactor. They should not do it.

One of the reasons of this is that RB engine is obtaining the code using the method formattedCode instead of sourceCode. (see formattedCode senders). Also some refactors do this (RBMoveMethodToClassSideTransformation>>#getNewSource RBMoveMethodToClassSideRefactoring>>#getNewSource...)
