Align on style for referencing methods in spec text

Description

Currently there are two styles for referencing methods in explanatory sections after listings, with () and without: getMessageInterpolator() vs. getConstraintDescriptor.
We should align on one style. Personally I'd prefer the former as it better communicates that a method is meant.
