fix: inner class parent is wrong when name formatted as Class$method$xxx

[ewt45]

inner class name format can be Class1$InnerClass1. but it can also be Class1$method1$InnerClass1 (example). In ClassInfo.splitAndApplyNames(), only the former situation is considered.

This pr is trying to cover the latter situation. If the inner class ClassInfo see its parent class as Class1$method1, parent classNode will not be found. In this case resolveParentClass() will try to split it again, into Class1 and method1, make sure Class1 exists and contains method method1, then set Class1 as inner class's parent.
