Many warnings when rendering the Member component

The Memberships/Member.vue component seems to be related to a large amount of the warnings seen in the Vue component tests. The exact error that occurs is very helpfully not shown.

[Vue warn]: Unhandled error during execution of render function 
  at <Member member= {
  id: 'member_id',
  level: 20,
  user: { id: 'user_id', email: 'james@test.me', display_name: 'James' },
  group: null
} ref="VTU_COMPONENT" > 
  at <VTUROOT>
[Vue warn]: Unhandled error during execution of scheduler flush. This is likely a Vue internals bug. Please open an issue at https://new-issue.vuejs.org/?repo=vuejs/core
