Container Registry Task Run error getting operation result --> Future#WaitForCompletion: the number of retries has been exceeded

This issue is related to #https://github.com/pulumi/pulumi-azure-native/issues/1713

Seems that querying the status of an Azure Container Registry Task.Run operation the url returned inside the `Azure-Asyncoperation` is not correct.

The address provided in that header has the `operationStatuses/` repeated two times.

`https://management.azure.com/.../resourceGroups/crazybike-main-rg/providers/Microsoft.ContainerRegistry/registries/crazybikemaincr/taskRuns/buy-build-task-run/operationStatuses/cb1b/operationStatuses/cb1b?api-version=2019-06-01-preview`

This leads to a 404 not found, the pulumi provider retries some times and then it gives up with the error.

Start with the Azure Container Registry Task.Run specification and the related issue #1713, then trace how the Azure-Asyncoperation URL is represented. Reproduce or inspect the reported URL containing the repeated operationStatuses segment; done means the specification no longer produces that malformed operation-status URL and the 404 scenario is addressed.
