Phoenix may incorrectly replace TableResultIterators after HBase region splits

UPSERT SELECT throws a StaleRegionBoundaryCacheException immediately after a split. On the other hand, an upsert followed by a select for example works absolutely fine

org.apache.phoenix.schema.StaleRegionBoundaryCacheException: ERROR 1108 (XCL08): Cache of region boundaries are out of date.
