Fix legacy errata upgrade scenario tests

[vsedmik]

Problem Statement

1. We have seen several post_upgrade failures for "rhel_contenthost-parametrized" upgrade scenario tests where the pre-data could not be fetched from the scenario_entities file:

failed on setup with "Failed: Invalid test parameter: rhel7. Test data not found."

The reason is that the pre-upgrade test names are now suffixed with -ipv4 so the scenario_entities hold items like this:

{"tests/upgrades/test_repository.py::TestSimpleContentAccessOnly::test_pre_simple_content_access_only[rhel7-ipv4]": {...}}

2. [POC] New-Style Upgrade Tests #14111 extended the ContentInfo.publish_content_view() method of with the name parameter without updating tests in the legacy upgrade scenarios, so now they cry:

TypeError: ContentInfo.publish_content_view() missing 1 required positional argument: 'name'

Solution

1. Pick the test names from scenario_entities including their suffix.
2. Make the name parameter optional.
