  Couple more fixes to Core Persistence implementation of RelationManager.
  Fixed test for EntityConnectionsIT.testGetConnectingEntities
  Fixed query test that got rid of the member surname.
  Reduced number of entities in dense search and fixed bug in test that was only searching 0 meters away when comments dictated it be 50000 kilometers.
  Fixed testDenseSearch, the test had code that was testing something commented out. Thus that part of the test is no longer needed
  Added a timeuuid for the creation of the test, otherwise there are issues when writing.

Changed the code to highlight the byte buffer error that exists.
Removed the Thread.sleep(1000) from almost all of the tests.
testExportOneOrganization needs the thread.sleep due to the number of entities it creates, and to let the writes be committed.
