Fix remainderPath in ChainTree.resolve

[aknuds1]

It doesn't look as if ChainTree.resolve sets remainderPath if a query would resolve to a partial path.

For example

await community.playTransactions(tree, [
  setDataTransaction('name', 'Name'),
]);
const result = await tree.resolve(['tree', 'data', 'name', 'child']);
// result.remainderPath should be ['child'], but will be ['tree', 'data', 'name', 'child'].
