Incorrect test class name for deep nested method

[EgorkaKulikov]

To Reproduce

1. Consider the following source code:

public class ClassWithStaticAndInnerClasses {
    public int z = 0;

    public static class PublicStaticClassWithPrivateField {

        public static class DeepNestedStatic {
            public int g(int x) {
                return x + 1;
            }
        }

        public class DeepNested {
            public int h(int x) {
                return x + 2;
            }
        }
    }
}

2. Locate the cursor inside h method.
3. Generate tests without mocks.

Expected behavior

Generated code is compilable, test class name is correct

Actual behavior

Current test class name leads to compilation errors.
