Doing full restore of OctoPrint, it cannot find this plug-in

[Taomyn]

I've been testing the 0.18 release of OctoPi and now that it's final I thought I should report this odd issue.

Each release of 0.18 during beta/RC I would perform a full backup of OctoPrint, boot the new image and perform a full restore. Every time I do this including after the final release I installed tonight I see this in file /home/pi/.octoprint/data/backup/unknown_plugins_from_restore.json

[{"key": "FriendlyBeeper", "name": "Friendly Neighborhood Beeper", "url": "https://github.com/techfreek/OctoPrint-Friendlybeeper"}]

When I check the plugin manager the plug-in is not installed but the data is present:

If I then install it manually from the plug-in manager it has no problem and even takes the old data. So not a critical issue just weird.

Any idea why this is happening? It's the only plug-in that has this issue and I have over 10 installed.

I actually have no idea. I've never tried restoring from a backup. Maybe I wasn't consistent with naming somewhere and it stopped it from finding it?

Sorry, I haven't really had a chance to look at this closely. Maybe it is fallout from OctoPrint/OctoPrint#3883? I'll have to see if I can take time to look closer and see what happened
