[Bug] Can't create CtPackage which the parent package name equals child package name

[treenwang]

Describe the bug
When use PackageFactory to create package. If the parent package name equals the child package name. Only one level of package will be created.

To Reproduce

Processing with Spoon:

    @Test
    void testCreatePackage(){
        CtClass<?> dClass = Launcher.parseClass("class A{}");
        CtPackage ctPackage1 = dClass.getFactory().Package().getOrCreate("duplicated.non_duplicated");
        Assertions.assertEquals("duplicated.non_duplicated", ctPackage1.getQualifiedName());//successful
        CtPackage ctPackage2 = dClass.getFactory().Package().getOrCreate("duplicated.duplicated");
        Assertions.assertEquals("duplicated.duplicated", ctPackage2.getQualifiedName());//failed
        CtPackage ctPackage3 = dClass.getFactory().Package().getOrCreate("duplicated.duplicated.duplicated");
        Assertions.assertEquals("duplicated.duplicated.duplicated", ctPackage3.getQualifiedName());//failed
    }

Output:

expected: <duplicated.duplicated> but was: <duplicated>
Expected :duplicated.duplicated
Actual   :duplicated

Operating system, JDK and Spoon version used

• OS: MacOS
• JDK: Java 11
• Spoon version: 10.1.1
