Steps to reproduce:

1. Create template with item and trigger
2. Get template import "source" data to use it further in api
3. Change trigger name
4. Send api request:

       "method": "configuration.importcompare",
       "params": {
           "format": "yaml",
           "rules": {
               "groups": {
                   "createMissing": true,
                   "updateExisting": true
               },
               "templates": {
                   "createMissing": true,
                   "updateExisting": true
               },
               "items": {
                   "createMissing": true,
                   "updateExisting": true,
                   "deleteMissing": true
               },
               "triggers": {
                   "createMissing": true,
                   "updateExisting": true
               }
           },
           "source": "zabbix_export:\n  version: '5.4'\n  date: '2021-05-14T13:18:53Z'\n  groups:\n    -\n      uuid: 3db9df077509459aaba109060764d431\n      name: apitemplate\n  templates:\n    -\n      uuid: 6bc7f3070e0842f3ace4a3606d8bb66e\n      template: apitemplate\n      name: apitemplate\n      groups:\n        -\n          name: apitemplate\n      items:\n        -\n          uuid: 477665165c274f5c98f10136aab236bc\n          name: apiitem\n          key: apiitem\n          triggers:\n            -\n              uuid: 4d23e9a921f84441bfcf7b74081c1c29\n              expression: last(/apitemplate/apiitem)=0\n              name: apitrigger\n"
       },
   

Result:
the output contains before and after blocks for the template and item, but there is no change there

Expected:
show before and after blocks only if it is different from before block.
Also, if one of the parameters is set to false, for example, for trigger set ""updateExisting": false", then before and after blocks should not be either.
