very confusing series of snap messages during a package update

[Seth Arnold]

Hello, I found this snap output today *very* confusing.

Trevinho updated the matterhorn snap. He announced it, so I knew it had been updated, I knew it should have been available. (I also *think* I put all packages on hold, because the autoupdate behaviour has been very frustrating.)

Please note:
- I run snap refresh because I know an update is available, and I think it cannot be installed already.
- snap tells me all snaps are up to date.
- Because this is a surprise, I ask for information on this specific snap.
- I am surprised that it hasn't been updated for eleven months: I *just* asked for it to be refreshed, and snap told me that there was nothing to do.
- I ask for a targeted refresh, because I can't recall if "snap refresh" will override the held package status.
- I'm told that an auto-refesh is in progress. Okay. "error: " isn't great, what I wanted to happen is actually happening, but it kind of makes sense.
- snap info matterhorn doesn't report that an update is in progress
- snap info matterhorn reports an error that the snap is disabled. This is very confusing.
- snap info matterhorn finally reports that the update is installed. Finally.

I think there's multiple places this could be smoother.

Thanks
