Todd Gamblin cb229f0842 Fixes #1720: spack reindex fails with invalid ref count. (#1867)
* Fixes #1720: spack reindex fails with invalid ref count.

- Database graph wasn't being built properly; dependencies were set up
  incorrectly in the nodes that ended up in the graph on reindex.

- Reworked _add to increment ref count properly and to always build
  bottom-up to make the logic simpler to understand.

* Add checks to ensure DB is a valid merkle tree.
