sharepoint-three-vm deployment errors

sharepoint-three-vm
### Issue Details
Attempted to deploy the sharepoint-three-vm template and received the following error:

New-AzureRmResourceGroupDeployment : 11:13:54 AM - Resource Microsoft.Resources/deployments 'ProvisioningSharepointVM'
failed with message '{

Inspect the sharepoint-three-vm template and PrepareSharePointServer.ps1, then reproduce the Azure deployment to examine the DSC extension failure. Done means the template deploys without the ConfigureSPServer errors for the missing xComputerManagement module and syntax block.
