Some LMS classes with group_info.authority_provided_id do not contain columns like group_info.tool_consumer_instance_name

In the Analytics Sandbox:

```
SELECT
gi.*,
g.*,
u.*
FROM
"group" g
left join "group_info" gi on g.authority_provided_id = gi.authority_provided_id
left join "user" u on g.creator_id = u.id
WHERE
g.created > '2020-01-01' AND
u.authority = 'lms.hypothes.is' AND
gi.context_title is not NULL AND
gi.tool_consumer_instance_name is NULL
order by
g.created DESC,
u.display_name
```

I find 33 classes made since 2020-01-01 that have a group_info row with no tool_consumer_instance_name. 31 Look like they’re Canvas, 2 look like Sakai.
LMS info is from tool_consumer_instance_guid for Sakai, and in custom_canvas_api_domain for Canvas.

Some of these are obviously test or sandbox courses, but some of them look like genuine LMS courses.

I've asked a partner school (they have 4 classes on this list and 2 classes that **do** have group_info.tool_consumer_instance_name) if there's a difference between their classes on their end, and I'll add that info here if they get back to me.
