Vuex bug with included resources

[Decipher]

Describe the bug
There appears to be an issue with the Vuex store handling of included resources when using the the new Entity Query include option.

I've seen the issue triggered when using HRM on the Entity Query examples, as well as within the Konstruukt site inside of a DruxtView component.

Needs further investigation.

To Reproduce

1. Have a View of content rendered via Druxt View
2. Have a Theme component for that view that iterates over the results and renders a DruxtEntity component with the settings property set to include a related resource:

<template>
  <div>
      <DruxtEntity
        v-for="result of results"
        :key="result.id"
        :type="result.type"
        :uuid="result.id"
        :mode="mode"
        :settings="{
          query: {
            include: ['field_video']
          }
        }"
      />
  </div>
</template>

This triggers a Vuex mutation error.

It is still possible to set the entity query include via the the Theme component:
Edit: It appears that this version can also cause the issue, so it is not a valid workaround.

<script>
export default {
  druxt: {
    query: {
      include: ['field_video']
    }
  }
}
</script>

Expected behavior
Included resources should be correctly added to the Vuex store and available both in server and client side.
