"Template diff confirmation" bypass when importing template containing YAML via Configuration->Hosts->Import

Steps to reproduce:

1. Prepare a YAML file containing templates
2. Navigate to Menu -> Configuration -> Hosts
3. In top-right corner click "Import"...
4. Select the YAML file

Result:

Templates from YAML file got imported

Expected:

A template import confirmation prompt showing a diff between the currently installed and new templates, just like it shows when importing via Menu -> Configuration -> Templates -> Import
