Fix trait errors with automerge

[gterzian]

With automerge 0.5, when copying some structs from the example, I get errors like:

41  | #[derive(Debug, Clone, Reconcile, Hydrate, PartialEq)]
    |                                   ^^^^^^^ the trait `AsRef<automerge::exid::ExId>` is not implemented for `ObjId`
42  | struct Address {
43  |    line_one: String,
    |    ---------------- required by a bound introduced by this call

This goes away when going back to automerge 0.4

I'm having the same issue. Our project needs some of the new features in automerge 0.5, including the new Patch API that replaces some of the older Observable API.

I started a PR to address this issue (the branch), but quickly became out of my depth trying to resolve Rust compiler issues related to automerge API changes.

I'm happy to help with this if needed.
