[#ZBX-19393] Undefined index in configuration.importcompare

(1) PHP runtime error "Undefined index" when missing rules in configuration.importcompare
Steps to reproduce:

Send request without host groups rules, templates or items, etc.

    "method": "configuration.importcompare",
    "params": {
        "format": "yaml",
        "rules": {
            "groups": {
                "createMissing": true,
                "updateExisting": true
            },
            "items": {
                "createMissing": true,
                "updateExisting": true
            }
        },
        "source": "zabbix_export:\n  version: '5.4'\n  date: '2021-05-14T09:24:01Z'\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"
    },

Result: totally empty output. Runtime errors:

Undefined index: templates [api_jsonrpc.php:63 -> CJsonRpc->execute() -> CLocalApiClient->callMethod() -> CConfiguration->importcompare() -> CConfigurationImportcompare->importcompare() -> CConfigurationImportcompare->compareByStructure() -> CConfigurationImportcompare->applyOptions() -> CConfigFile->{closure}() in include/classes/import/CConfigurationImportcompare.php:235]
TypeError: array_key_exists() expects parameter 2 to be array, null given in /ui/include/classes/import/CConfigurationImportcompare.php:290
Stack trace:

#4 /ui/include/classes/core/CJsonRpc.php(75): CLocalApiClient->callMethod()
#5 /ui/api_jsonrpc.php(63): CJsonRpc->execute()
#6 {main}

Expected result: no errors. Output maybe:

{
    "jsonrpc": "2.0",
    "result": [],
    "id": 1
}

(2) Undefined offset when import new template with graph and unselect "Create new" for items and discovery
Steps to reproduce:

Create template
Add item, graph with this item and discovery rule
Export file
Delete template
Import file
Uncheck "Create new" for Items and Discovery rules
Import
zbx_export_templates_graph.yaml

Result:

Undefined offset: 10468 [zabbix.php:22 -> require_once() -> ZBase->run() -> ZBase->processRequest() -> CController->run() -> CControllerPopupImport->doAction() -> CApiWrapper->__call() -> CFrontendApiWrapper->callMethod() -> CApiWrapper->callMethod() -> CFrontendApiWrapper->callClientMethod() -> CLocalApiClient->callMethod() -> CConfiguration->import() -> CConfigurationImport->import() -> CConfigurationImport->processDiscoveryRules() -> CConfigFile->{closure}() in include/classes/import/CConfigurationImport.php:1320]
