Spring Polish resolveArgument method in RequestResponseBodyMethodProcessor

String name = Conventions.getVariableNameForParameter(parameter);

The above code is only used in conditional statements. So I moved it into the conditional statements. With this, we can expect a slight performance improvement in some case.

I merged this refinement. For your question, I am not sure how common it is, maybe @poutsma or @rstoyanchev know more.
