Fix minor issues and ensure compatibility with the latest CiviCRM version

Issue:

The current fastactionlinks wasn't displaying the fast action links under the action column when used with advanced search.

Expected Results: Fast action links should be visible under the action column.

Actual Results: The fast action links were not visible.

Proposed Solution:

Since the commit in civicrm-core, fastactionlinks has been unable to fetch the value of _ufGroupID, causing condition checks to fail.

To resolve this, we fetch the same value from another variable like this: $object->get('uf_group_id');. (Thank you @colemanw for your suggestion.) This change prevents the condition from failing. Additionally, other minor adjustments have been made to ensure proper functionality.

Please review the changes.

Thank you!
