Previously protected methods on refinements could never be called because they were seen as being "defined" on the hidden refinement ICLASS. This commit updates calling refined protected methods so that they are considered to be defined on the original class (the one being refined). This ended up using the same behaviour that was used to check whether a call to super was allowed, so I extracted that into a method. [Bug #18806]
