az pipelines refuses to show me release for id it says exists

- If the issue is to do with Azure CLI 2.0 in-particular, create an issue here at [Azure/azure-cli](https://github.com/Azure/azure-cli/issues)

### Extension name (the extension in question)
az pipelines

### Description of issue (in as much detail as possible)

I get VS402936: Release pipeline with ID 6 does not exist. Specify a valid ID and try again.

It states - to me - that the release id 6 does not exist when i explicitly attempt to view it with the command:

`az pipelines release definition --id 6`

Seems reasonable except the definition id is returned to me as 6 when i list all releases:

`az pipelines release definition list`

The release definition exists in the Azure Devops portal. I can only imagine that folders in the release section are some how interfering as it is the only difference I have accounted for here.

Anybody got any ideas? How can this be? What am I missing?
