Description

When CQs are installed at Geode server, they dynamically analyzes incoming updates/creates or deletion entries in the region.

If we have CQ something like "select * from /region i where i=1" and put some values with i=0, and after that we change it to 1 and again to 0 several times we got on listener some CREATE  and some UPDATE when it fulfilling cq condition.

The issue can be easily reproduced by geode-examples by modifying geode-examples/cq/src/main/java/org/apache/geode_examples/cq/Example.java to put  some entries with transactions and then update it.
