Description

There are currently two potential NPEs in LuceneServiceImpl during index creation on an existing region.

The first occurs when a bucket is moved during indexing:

        at org.apache.geode.cache.lucene.internal.LuceneServiceImpl.createLuceneIndexOnDataRegion(LuceneServiceImpl.java:294)
        at org.apache.geode.cache.lucene.internal.LuceneServiceImpl.createIndexOnExistingRegion(LuceneServiceImpl.java:277)
        at org.apache.geode.cache.lucene.internal.LuceneServiceImpl.createIndex(LuceneServiceImpl.java:257)
        at org.apache.geode.cache.lucene.internal.LuceneServiceImpl.createIndex(LuceneServiceImpl.java:226)
        at org.apache.geode.cache.lucene.internal.LuceneIndexFactoryImpl.create(LuceneIndexFactoryImpl.java:70)

The second occurs when the LuceneEventListener attempts to process events before the Lucene Index has been fully initialized (and userRegion set).
