Azure Stack installation checks for company admin role instead of global admin

Running "DRIVE:\AzureStack_Installer\asdk-installer.ps1" after booting into CloudBuilder.vhdx checks for company administrator role instead of global administrator in "C:\CloudDeployment\Setup\Common\AzureADConfiguration.psm1", line 339.
If the user installing ASDK has only global administrator role, installation fails with error message saying that the user does not have access to any tenants.

[Documentation states that only global administrator role is required for installation.](https://docs.microsoft.com/en-us/azure-stack/asdk/asdk-install?view=azs-2008)
