v9.1.0 breaks hierarchical browsing when tags exist

[tunesmith]

In v8.3.0, if you incremented a counter of a name, then in graphite-web or grafana, you were still able to browse it hierarchically.

In our case, we also have datadog environment variables. In v9.1.0, those DD_* env variables are automatically added as tags, which is fine, but then it also means that the counter name is added as a tag:name instead, which means the counter name cannot be browsed hierarchically anymore.

I'm fine with having tags, but in the cases where I don't care about the tags while browsing, I'd prefer to be able explore that tag hierarchically in the frontends. Am I missing something basic about how this is intended to work? Can the ability to browse these metric names be hierarchically be restored, even if they were sent with tags?
