Empty/wrong trigger of Bodhi updates triggered by a user Koji build

[nforro]

For a Bodhi update triggered by a successful Koji build triggered by a user (not Packit), get_project() returns None and the update shows up in the dashboard with a / trigger (because repo_namespace and repo_name are not populated):

packit-service/packit_service/service/api/bodhi_updates.py

Lines 46 to 49 in d95578f

	if project := update.get_project():
	update_dict["project_url"] = project.project_url
	update_dict["repo_namespace"] = project.namespace
	update_dict["repo_name"] = project.repo_name
