this.sessioncluster=true breaks sessions

Description

We store session data in a database. When our Application.cfc includes the line this.sessioncluster=true the standard items are written for a new session (timecreated, sessionid, lastvisit) but session variables created by our application are not written to the database.

If we remove this.sessioncluster=true or change the session storage setting to "memory" the problem goes away. The same applications worked fine on version 5.0.0

I noticed that with this.sessioncluster=true the session data seems to be overwritten... the timecreated data is updated for each page request and always matches the lastvisit. When I remove this.sessioncluster=true this behaviour goes away... the timecreated stays the same while the lastvisit is updated and other data is written.

Environment

Windows Server 2012R2, Windows 8.1. Fresh install from current Windows installer.

the clustering feature has changed between 5.0 and 5.2 to handle better synchronisation of multiple server storing at the same time.
But 5.2 should be able to load sessions from 5.0, but the other way around of course it is not possible. 5.0 does not understand 5.2 sessions.

I've analyzed this ticket a lot & confirmed the issue with changing in the format for cf_session_data. In lucee 5.0.x.x, session data stored in JSON format, but in lucee5.2.x.x version session data's were stored as encryption of data. If we switch from 5.0.x.x to 5.2 version. It throw error like

It breaks the session.

NOTE: If we have session data in 5.2.x.x version with encrypted value in cf_session_data. If we changed to 5.0.x.x version. It throw error like

If we switch 5.1.0.x version to 5.2.x.x version. It throw error like:

Issue occurs only when changed format data on cf_session_data
