IAVL mostly uses panics for error handling. It should return errors instead.

I am experiencing this issue. Instead of Panic IAVL should return errors in order to be able to handle them on the upper layer.

panic: Value missing for hash 5c762dd92f621bd3df4f93cdd153d5639590de63f8be117c317615faab68c0c6 corresponding to nodeKey n\v-�/b�O���S�c���c��|1v��h��

Very much in favor of this, especially since this is a library.

vochain: temporarily recover some iavl panics
742111c 
We've seen a handful of panics from iavl in Envelope and EnvelopeList
calls.

Until cosmos/iavl#212 is fixed by
upstream, try to return or log an error instead of crashing the entire
gateway.

We shouldn't see these panics anymore after we fixed the data races in
the previous commit. Still, be extra safe.

For #262.
