Get-AzureVMSqlServerExtension was not reporting back "AutoBackup" and "AutoPatching" configurations.

SQL VSTS# 4295279 - Extension status cmdlet does not show Backup/Patching settings

Issue:
- Extension name was not fully qualified when we were enumerating Extension Statuses

Fix:
- construct fully qualified Extension handler name like Microsoft.SqlServer.Management.SqlIaaSAgent
- This approach is similar to DSC extension's get cmdlet
