[core] java.lang.* type name collisions

[nitram84]

I would like to report some type name collisions with java.lang.* classes. I tested with latest git version and of course the option "Use import statements" is enabled. This issue is similar to #1406.

Case 1: Same package

package jadx.test;

public class System {
  public static void doSomething() {
  }
}

package jadx.test;

public class JavaLangTypeCollision {
  public void doSomething() {
    System.doSomething();
    java.lang.System.out.println("Hello World");
  }
}

Case 2: Inner classes

public class JavaLangTypeCollision2 {
  public void doSomething() {
    System.doSomething();
    java.lang.System.out.println("Hello World");
  }

  public static class System {
    public static void doSomething() {
    }
  }
}

Case 3: Same class (my favorite example)

public class System {
  public static void main(String[] args) {
    java.lang.System.out.println("Hello world");
  }
}

Fixed. Thank you for test cases 👍
