Fix bug in chronologize(key, record)

[CON-72] was wrong commit message, which I later changed to [CON-71] to be correct.

Refer to [[CON-71] ](https://cinchapi.atlassian.net/browse/CON-71?jql=project%20%3D%20CON%20AND%20status%20in%20(Open%2C%20%22In%20Progress%22%2C%20Reopened)) for the issue. 

Fix in the bug:

* The previous implementation contains a bug in *updateChronologize* method, because it took the wrong condition check. It compared changes in the **result** with **new audit**, but should have compared **old audit** with **new audit**.
* New test has been added with rigorous checks in each set of values from the returned mapping.
