9160: Do not try to auto-import simple enum names in switches, that are 'in scope' due to enum switch target typing.

[lahodaj]

Consider code like:

package test;
import static test.E.A;
public class Test {
    private void test(E e) {
        switch (e) {
            case A:
            case B:
            case C:
                System.err.println(A);
                break;
        }
    }
}
enum E {
    A, B, C;
}

And copy&paste to another file. This should not propose to add imports for B and C (it should for A, as that's used in the System.err.println).

Only eyeballed this, but logic makes sense to me. I have a minimal nitpick for the test: A method that does a clip board copy should not be named doCopyAndPaste. 😄

Suggested change

	private FileObject doCopyAndPaste(String from, String sourceLevel) throws Exception {
	private FileObject doCopy(String from, String sourceLevel) throws Exception {
