Steps to reproduce:

I'm not sure about the way to reproduce the issue. I have an old template coming from Zabbix 2.2. 'Template OS Linux'. On this template, some triggers are of type 7.

1. Get an old template without Event Problem Generation option selected
2. Select and export template
3. Error 'Invalid tag "type": unexpected constant value "7"'
4. Repeat operation with API configuration.export
5. Same 'Invalid tag "type": unexpected constant value "7"'
6. Repeat operation with API
   template.get(templateids=10001, 
                                     output='extend', 
                                     selectTags='extend',
                                     selectTemplates='extend',
                                     selectParentTemplates='extend',
                                     selectHttpTests='extend',
                                     selectItems='extend',
                                     selectDiscoveries='extend',
                                     selectTriggers='extend',
                                     selectGraphs='extend',
                                     selectApplications='extend',
                                     selectMacros='extend',
                                     selectScreens='extend')
    

Result:

{{Exemple of trigger coming from api template.get {'triggerid': '13243', 'expression': '

>60', 'description': 'Disk I/O is overloaded on {HOST.NAME}', 'url': '', 'status': '0', 'value': '0', 'priority': '2', 'lastchange': '0', 'comments': 'OS spends significant time waiting for I/O (input/output) operations. It could be indicator of performance issues with storage system.', 'error': '', 'templateid': '0', 'type': '0', 'state': '0', 'flags': '0', 'recovery_mode': '0', 'recovery_expression': '', 'correlation_mode': '0', 'correlation_tag': '', 'manual_close': '1', 'opdata': ''}}}

Expected:
Trigger type should always be 0 or 1. All non 1 value in database should be changed to 0
