Steps to reproduce:

1. Open Data collection -> Hosts
2. Click on the context menu, for the host, which already have templates assigned. (templates should have parameter wizard_ready: yes)
3. Select Host Wizard
4. Proceed to Template selection screen in Host wizard
5. See the available filters

Result:
There is no Linked template filter, which should be present, if host already has templates assigned, that are supporting Host wizard.
See video:

Expected:
When editing a host (which has templates assigned), using Host wizard - "Show templates" filter should be present. (should work same as on release/7.4)
