fixes example should get the whole tree

[thisconnect]

JavaScript implementation would only log the tree for 'a' which would log []

Pretty sure this is an example bug

[thisconnect]

also the result is an array, should I update this?

ipfs.dag.tree('zdpuAmtur968yprkhG9N5Zxn6MFVoqAWBbhUAkNLJs2UtkTq5', errOrLog)
// Logs:
// a
// b
// b/0
// b/1
// b/2
// c
// c/ca
// c/ca/0
// c/ca/1
// c/ca/2
// c/cb

In js-ipfs it is:

// Logs:
// [ 'a',
//   'b',
//   'b/0',
//   'b/1',
//   'b/2',
//   'c',
//   'c/ca',
//   'c/ca/0',
//   'c/ca/1',
//   'c/ca/2',
//   'c/cb' ]

[thisconnect]

dag.tree should return an array https://github.com/ipfs/interface-ipfs-core/blob/master/src/dag.js#L369-L372

thanks for catching this @thisconnect :)

My first time playing with js-ipfs, instead of js-ipfs-api + go-ipfs. It's great to have dag api :) works nicely so far.
