When querying the templates, each template returned has the "name" filled, even if no visible name was entered. This causes a problem when trying to update templates as the API client does not know if a visible name was set or not.

Example:

• The default installation has no visible name set for "Template_Cisco_PIX515E"
• The API returns "Template_Cisco_PIX515E" for both "host" and "name".
• "name" should be null or "" to indicate that no name was set.

I have skipped a possible bugfix as I don't know if that's intented or conflicts in other areas of Zabbix.
