Checkmk Werk 12752: jira notification: Fix empty rule on edit if rule was created pre 1.6.0p18

ID: 12752 Title: jira notification: Fix empty rule on edit if rule was created pre 1.6.0p18 Component: Notifications Level: 1 Class: Bug fix Version: 2.1.0i1 With werk #11202 the option "Site custom field ID" was introduced. If you configured rules before that werk and tried to edit such rule in versions from 1.6.0p18 upwards, an empty rule was shown. A workaround was, to edit the file /var/check_mk/conf.d/wato/notifications.mk and add the key value pair "'site_customid': ''" to the "jira_issues" notification rule.
