Host edit modal window is closed when Enter key is pressed

Steps to reproduce:

1. Open host edit modal window
2. Enter existing template name in Template search box
3. Press Enter

Result:
Template is not added and modal window is closed with success message.

Expected:
Template is added to template search box, modal stay opened. Same behavior as for when configuration is opened as page.
