Export script generates incomplete ARM template

The export script is generating an incomplete ARM template for our factory, content:

```json
{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"factoryName": {
"type": "string",
"metadata": "Data Factory name",
"defaultValue": "factory-name"
}
},
"variables": {
"factoryId": "[concat('Microsoft.DataFactory/factories/', parameters('factoryName'))]"
},
"resources": [
{
"name": "[concat(parameters('factoryName'), '/default')]",
"type": "Microsoft.DataFactory/factories/globalparameters",
"apiVersion": "2018-06-01",
"properties": {},
"dependsOn": []
}
]
}
```

This template should at least contain 1 copy data activity, 2 datasets, 2 linkedServices, 1 trigger, but they all are missing.

Similar to https://github.com/Azure/Azure-DataFactory/issues/288,
We are getting warnings that `@microsoft/azure-data-factory-utilities` cannot find models for types 'ipeline', 'inkedService', 'rigger', 'ataset', with these warnings occurring the same number of times per type as we have resources for them, so for example 2 times for our linkedServices, etc., which seems oddly related.

```sh
WARNING === ModelService: synchronizeInternal - Failed to find model for the resource, ignoring this resource. Error: {"stack":"Error: Not able to find model for type - ipeline and subType - undefined\n at e.getModelByResourceType (C:\\path\\to\\project\\downloads\\main.js:2:4235306)\n at e.
