Describe the expected behavior
in models/LogsStore.js when I use SimpleLog without snapshotProcessor everything is OK,

but

when i try use SingleLog with snapshotProcessor in console log throw error:

Uncaught Error: [mobx-state-tree] Failed to resolve reference '2' to type 'SimpleLog' (from node: /highlighted)

Why used references not working with types.snapshotProcessor?

Thanks:)

Minimum code

export const SimpleLog = types.model("SimpleLog", {
  id: types.identifier
});

export const SingleLog = types.snapshotProcessor(SimpleLog, {
  preProcessor(sn) {
    return {
      id: `${sn.time}`
    };
  }
});

export const LogsStore = types.model("Logs", {
  ref: types.maybe(types.reference(SimpleLog)),
  obj: SingleLog
});

const Logs = LogsStore.create({
  ref: "2",
  obj: {
    time: "2"
  }
});

const r = Logs.ref;

TODO: add exception when types.reference is not passed a model type? (probably the same for safe ref)

is there any workaround for this issue?
