Description of problem:

Based on https://bugzilla.redhat.com/show_bug.cgi?id=2122945, The "Entity version collison" issue was expected to be fixed in Satellite 6.12 and candlepin-4.2.6-1, candlepin-4.1.15-1 

But Satellite 6.13 comes with candlepin-4.2.3-1 and if i delete the exported manifest and reimport a new manifest, The same issue is very easily reproducible. 


Version-Release number of selected component (if applicable):

# rpm -q candlepin satellite
candlepin-4.2.3-1.el8sat.noarch
satellite-6.13.0-4.el8sat.noarch

How reproducible:

Always if followed a specific sequence of actions


Steps to Reproduce:

* Installed Satellite 6.13 ( latest snap )

* Imported a manifest 

* Enabled a few repos ( but none of them needs to be synced )

* Deleted the imported manifest from the satellite UI

* Created a new allocation, exported its zip, and tried to import it back to Satellite.


Actual Results:

Expected Results:

No such errors. 


Additional Info:


Based on https://bugzilla.redhat.com/show_bug.cgi?id=2122945, it should be already fixed in 6.12 and candlepin version candlepin-4.2.6-1, candlepin-4.1.15-1 

Based on https://bugzilla.redhat.com/show_bug.cgi?id=2123384 it's fixed in candlepin-4.2.6-1

So do we need updated candlepin version in Sat 6.13 i.e. candlepin-4.2.6-1 or above ?
