The Release workflow fails when there are no changelog entries in the release

[quba42]

Happens during the "Update Redmine" step during publish, so most of the release has already happened (packages are updated on pypi and rubygems, etc.).

The error encountered is:

python3 .ci/scripts/redmine.py $REDMINE_QUERY_URL $MILESTONE_URL $RELEASE
Traceback (most recent call last):
  File ".ci/scripts/redmine.py", line 27, in <module>
    status = redmine.issue.get(int(issue)).status.name
ValueError: invalid literal for int() with base 10: ''

See here for the full workflow: https://github.com/pulp/pulp_deb/runs/4223060338?check_suite_focus=true

Expectation:

If there are no issues in the release, then .ci/scripts/redmine.py does not need to do anything, and should just return 0!

Release steps not performed because they come after the error:

• Create release on GitHub
• Cleanup repository before making changelog PR
• Stage changelog for master branch
• Create Pull Request for Changelog

=> The changelog steps might also need some special handling to deal with this special case of "no changelog entries".
