When no host is specified in the trigger list filter, the hostid is missing from the link of the trigger displayed in the “Depends on” list. As a result, the super admin user receives an access denied error when clicking on that trigger.

Steps to reproduce:

1. Login under super-admin,
2. Navigate to the trigger list,
3. Clean page filter (remove hosts from it),
4. Select one trigger from "Depends on" list and click on it.

Result:  Access denied error message.

Link content: 

href="zabbix.php?action=popup&popup=trigger.edit&triggerid=22387&hostid=0&context=host" 

Expected: When host is selected, admin is able to open the same dependent trigger form.
