Git repo origins are now removed in CI jobs, so our detection of project
short name from looking at the git remote now fails. This resulted in
release announcements linking to "null" instead of the actual project
location [0].
This updates the script logic to detect if that is the case and fall
back to getting the repo name from the directory, which should be safe
in a CI job since there is no manipulation of the clones repo directory
name.
Also cleans up an unused variable that was left from a previous
refactoring.
