`has_jira` filter doesn't take Finding Group JIRA issues into account

[valentijnscholten]

The finding list pages in Defect Dojo have a filter to search for Findings that have or do not have a JIRA issue.

For findings that are in a group and that group has a JIRA issue, this filter currently doesn't work. The filter only checks if the finding itself has JIRA issue.

Question is should we:

1. Update the filter to match any JIRA issue, either for the Finding or the group that finding is in
2. Add an extra filter has_group_issue to filter for JIRA issues linked to the group the Finding is in
3. Both
4. Do nothing
