Graph items of templates are added without template name

1) Open a template host
2) Create a graph (or open an existing one)
3) Add a new item to the graph - the template name is not added to item name (for example: Zabbix busy trapper processes, in %)
4) Save graph
5) Open the saved graph - the template name is added to item name (for example: Template App Zabbix Server: Zabbix busy trapper processes, in %)
