AzureRM unable to replicate Event Hub because of $Default consumer group

I am encountering what is apparently a longstanding issue that when trying to recreate an Azure Event Hub, the TF resource manager for Azure refuses to create a consumer group with the name “$Default” despite the fact that this consumer group is created automatically by Azure on Event Hub creation, and even if one adds additional consumer groups, Azure does not allow one to delete the default.

I see via Googling that this was raised as an issue in the 2x release and marked fixed but apparently the issue has re-appeared in 3x, and I was unable to pick up the thread at this point.

Is there a fix or a workaround?
