Fix visibility of issue enforcement setting

This change ensures that Jira issue association is only enabled when
project has a `jira_issues_integration` license and an active Jira
integration. When the above conditions are not met, the `Require an
associated issue from Jira` project setting is not shown.

Changelog: fixed
