Remove redundant .or(named("getParts")) from ExtractContentParametersAdvice matcher

ExtractContentParametersAdvice applied to getParts() is always a no-op:
it increments/decrements CallDepthThreadLocalMap but never fires since
_contentParameters is always null at that point. GetFilenamesAdvice and
GetFilenamesFromMultiPartAdvice handle getParts() exclusively.
