Receive mutation doesn't add items in a "Vue-reactive" way

[luthian]

I'm using this package and the standard receive mutation appears to not be adding new items to the byId state in a "Vue-reactive" way. When I mapped the list getter to a computed value and used that as a v-model to a Vuetify combovox, the computed value was always empty even after the state.byId had been updated.

The README file says that the code generated for this mutation does this:
response.forEach(datum => Vue.set(state.byId, datum.id, datum));
but the project code in mutations.js does this:
response.forEach(datum => (state.byId[getKey(datum)] = datum));

Should the receive mutation be updated to use Vue.set? I can submit a pull request with this change.
