Added a bit of fuzz testing over mtree splits

Browse Source 
This isn't the greatest coverage as we don't have a verifiable simulation.
Simulating the splitting-bucket-tree that is the mtree is tricky.

So right now this mostly just checks there's no internal assert failures and
if we have the expected number of entries afterwards.
