Migrations not working from v0.8.0

[philrz]

I've only focused on Brim GA tag v0.8.0 for this specific repro, but after talking to @jameskerr it sounds like this is a general issue with migrations not having been considered for "from" releases other than GA tag v0.9.1.

In the attached video, I started out running v0.8.0, import a small pcap, then perform a couple queries to populate my History. I then close the app and upgrade to a release artifact based on Brim commit dc488b1. On the first launch into the app, other than a "Failed to fetch" message that I had to Dismiss, it looks as if maybe it cleared all app state, which might be an appropriate thing to do in this situation. However, when I close the app yet again and reopen, now I see ghostly remnants of my prior Space: A nameless entry in the Recent Spaces list, empty "star" entries in the History panel, etc.

Verified in Brim commit 9373ee8. In the attached video, I'd already performed the repro steps in v0.8.0 to have a populated search history, but now upgrade to a new release artifact based on commit 9373ee8. As shown, now my History entries are cleared out, indicating the state has been reset as promised in the linked PR. However, my Space is still present, and I can run queries against it and it starts to re-populate my History. Since the original bug also showed different behaviors between repeated app launches, I did that here as well and everything was still healthy after the extra close & relaunch.

Thanks @jameskerr!
