Jira issue not created

When Jira is connected, a delivery's issue goes to the first that applies: what was named (jira: KEY or jira: KEY-12, or the portal form's Jira fields), then the project mapped to one of its repos, then the project mapped to its Slack channel, then the default project. If none is set, the project doesn't exist, or Jira errors, the delivery says why in its thread and activity feed and carries on without one. An existing issue is only linked if Jira can see it. Fix it in Integrations → Jira (default project, per-repo and per-channel rows). A delivery split per repo gets one issue per repo.
