Steps to reproduce:

1. Create template with one item and trigger
2. Create host and link to template
3. Change host's item History storage period 
4. Change host's trigger priority and disable trigger

Result:
See attached, host.xml does not contain any diffs between host and template

Expected:
host.xml does contain any diffs from templates. If we export\import host with XML, we expect host exactly what it was

It will be usefull for "XML backup" and save Zabbix configuration as code and review this, for example when we use https://gitlab.com/devopshq/zabbix-review-export
