[Bug]: Simple case with wrong package name of used external class

[salmonb]

Describe the bug

When asking to parse 2 classes a.A & b.B and a.A is using an external class c.C through b.B (see simple code below), the parser reports that a.A is using b.C instead of c.C (C belongs to package c and not b).

Source code you are trying to analyze/transform

// First file A.java
package a;

import b.B;

public class A {

    public static void callC(B b) {
        b.getC().xxx();
    }

}

// Second file B.java
package b;

import c.C; // external source not provided

public interface B {

    C getC();

}

Source code for your Spoon processing

Launcher launcher = new Launcher();
launcher.addInputResource(inputSource);
CtModel model = launcher.buildModel();

for (CtElement ctClass : model.getElements(e -> e instanceof CtClass || e instanceof CtInterface)) {
    CtType<?> ctType = (CtType<?>) ctClass;
    System.out.println(ctType.getQualifiedName() + " is using:");
    for (CtTypeReference<?> type : ctType.getUsedTypes(true)) {
        System.out.println(" - " + type.getQualifiedName());
    }
}

Actual output

a.A is using:
 - b.C
 - b.B
b.B is using:
 - c.C

Expected output

a.A is using:
 - c.C
 - b.B
b.B is using:
 - c.C
