Permit groups with >1 operation in status check.

Description

While looking into #547 and discussing with @b-butler, I found out that the refactors of the status code from #417 might have broken group status updates.

Here's the output I get with these changes on commit bbeabe1 (compare with output in #547, which does not show band_path_group or dos_group).

Motivation and Context

Partially fixes #547.

Status tests are failing and need to be fixed. Also, is this PR planning on implementing any decisions from #547?

@b-butler Both of those reasons are why this is still a draft. I just tagged you as a reviewer so you could see what I meant from our Slack conversation. I am going to wait until #547 has more consensus to work on this further, but this draft PR fixed my immediate need for group status information.

Closing -- this prototype design is not as good as what we proposed in #547 (comment).
