AdvancedDatastore.ensureIndexes doesn't handle fields subtypes properly with version 1.3.2

[dinosavings]

Unit test:

public void testBadIndexing() {
datastore.ensureIndexes(B.class);
datastore.ensureIndexes(TestObject.class);
}

@Entity
public static class TestObject {
    @Indexed
    private Long id;
    @Embedded
    private A a;
}

public static class A {
    @Indexed
    private Long id;
}

@Entity
public static class B extends A {
    @Indexed
    private String url;
}

Running testBadIndexing() generates the following exception

org.mongodb.morphia.mapping.MappingException: The path 'a.url' can not be validated against 'MyUnitTest$TestObject' and may represent an invalid index

morphia version: 1.3.2
mongo driver version: 3.4.2

This was working fine with morphia version .111.

I have absolutely the same issue!

While debugging through the implementation I have found that IndexHelper collects indexes from sub-classes (derivated / extended classes) that may contain new fields whereas it should have collected the indexes from parent (super-classes).

That is why index validation logic yields about incorrect index.

Please fix it.
