DevTest Labs does not set ARM template parameter _artifactsLocation correctly

[Yvand]

When DevTest Labs deploys an environment from an ARM template, it misses the trailing '/' on parameter _artifactsLocation.
So value currently looks like: https://xxx.blob.core.windows.net/artifacts/SharePoint-AllVersions.132932726444650209/SharePoint-AllV1335581893

This is bad: It should have the same behavior as ARM function deployment().properties.templateLink.uri, which includes a trailing '/' at the end.
So value should looke like: https://xxx.blob.core.windows.net/artifacts/SharePoint-AllVersions.132932726444650209/SharePoint-AllV1335581893/

Impact on the ARM templates for DevTest Labs:

• They have to manually add the trailing '/' to the value passed in _artifactsLocation by DevTest Labs.
• Their default value of parameter _artifactsLocation cannot / should not be deployment().properties.templateLink.uri, because it would not reflect the actual format of the value at deployment time.
• Since the templates cannot use deployment().properties.templateLink.uri as default value, this causes a validation error when using ARM TTK to validate the templates syntax.
