Description of problem:
When incremental syncable export fails for a valid reason (like filtered vs. unfiltered CV version is incrementally exported), hammer does not show the reason message from the production log.

Version-Release number of selected component (if applicable):
6.13.0 snap 11

How reproducible:
always

Steps to Reproduce:
1) Sync some RH repo like Ansible, sync it (with IMMEDIATE policy!)
2) Create a CV, add the repo, add a filter (include rpm `ansible`, not `ansible-test` nor `sshpass`), publish
3) Export complete, check content -> 32 pkgs

1. hammer content-export complete version --format syncable --organization-id 1 --id <CVV_id>
   4) Add include filter for sshpass, publish.
   5) Export incremental, check sshpass is exported.
2. hammer content-export incremental version --format syncable --organization-id 1 --id <CVV_id + 1>
   6) Remove both filters, publish.
   7) Export incremental, check the result and production.log
3. hammer content-export incremental version --format syncable --organization-id 1 --id <CVV_id + 2>

Actual results:
[root@sat ~]# hammer content-export incremental version --format syncable --organization-id 1 --id 15
Could not export the content view version:
400 Bad Request

In production.log:
2023-02-22T06:10:45 [E|bac|da9f3a38] Cannot incrementally export from a filtered and a non-filtered content view version. The exported content view version 'CV-RH 3.0' cannot be incrementally updated from version '2.0.'. Please do a full export. (Katello::Pulp3::ContentViewVersion::ExportValidationError)

Expected results:
[root@sat ~]# hammer content-export incremental version --format syncable --organization-id 1 --id 15
Could not export the content view version:
Cannot incrementally export from a filtered and a non-filtered content view version. The exported content view version 'CV-RH 3.0' cannot be incrementally updated from version '2.0.'. Please do a full export.
