Problem description: it is possible to sort the list of web scenarios by Host/Template name, but it is not possible to do the same for items, triggers, graphs and applications

Steps to reproduce:

1. Open configuration of any host/template
2. Open the list of web scenarios and configure the filter to display web scenarios of all hosts/templates
3. Attempt to sort the list of web scenarios by Host/Template column - notice that the column title is clickable and the list gets sorted.
4. Attempt to do the same for host/template items, triggers, graphs or applications

Result:
"Host" or "Template" column header is not clickable, it is not possible to sort items, triggers, graphs or applications by host/template name.
Expected:
it should be possible to sort items, triggers, graphs or applications by host/template name, as it is done for web scenarios.
