RCS1016 result doesn't compile fix

[jamesHargreaves12]

If there is a trailing comment after an arrow expression then applying RCS1016 will produce code that fails to compile as the trailing '}' will be appended to the comment.

For example:

string P => null; // some comment

becomes:

string P { 
    get { return null;// some comment}
}

The cause is that the WhitespaceRemover is removing newlines even if they are preceded by a comment.
