preparations for js-ipfs 0.33

First ran the tests with master:

$ git fetch && git pull origin master
From https://github.com/orbitdb/ipfs-log
 * branch            master     -> FETCH_HEAD
Already up to date.

$ rm -rf node_modules && npm install && npm run test
290 passing (2m) # All tests pass!

Then I applied @alanshaw's upgrades...
