Closed virtualbox nodes after host reboot should not pretend to be removed by lein pallet down

[dgtized]

After rebooting my laptop with a node running I had problems getting lein pallet up and down working correctly. lein pallet up was trying to use my ssh key instead of the vmfest one despite it being a new node, and lein pallet down always reported it was removing a node. Lein pallet nodes reported a single node without an ip. After about an hour of confusion due to this, I opened up VirtualBox and manually deleted the node, which was simply off. After that lein pallet up worked fine.

The issue here is that lein pallet down claims it's removing a node, but doesn't, presumably because for safety it can't remove stopped nodes. If it can't actually remove the node, it should report that it can't.
