Nodes are closed forever on redo

[felzix]

Running these commands causes all nodes in the buffer to close. They never open again.

1. origami-reset
2. origami-forward-toggle-node
3. origami-undo
4. origami-redo

The nodes do not open when I run any of these commands: origami-open-node, origami-open-node-recursively, and origami-open-all-nodes. I have to run origami-reset to open the nodes again.

NOTE: I'm using the melpa version of the original package, not this package. The related code looks the same but I haven't verified that. I posted here because this is active.
