OrganizeImports fixed for clashing star imports.

[dbalek]

Running Organize Imports action on the following source code removes the necessary import for java.util.List

package javaapplication;

import java.awt.*;
import java.util.List;
import java.util.*;

public class JavaApplication {

    public static void main(String[] args) {
        List a;
        Map m;
        AWTEvent e;
    }
}

This PR should fix this problem.
