Making fork repro test smaller

[cameronvoell]

test('groups cannot fork', async () => {
  const [alix, bo, new_one, new_two] = await createClients(4)
  // Create group with 2 users
  const alixGroup = await alix.conversations.newGroup([
    bo.address,
    new_one.address,
    new_two.address,
  ])

  // sync clients
  await alix.conversations.sync()
  await bo.conversations.sync()
  const boGroup: Group<DefaultContentTypes> = (await bo.conversations.findGroup(alixGroup.id))!

  // Remove two members in parallel
  // NB => if we don't use Promise.all but a loop, we don't get a fork
  console.log('*************libxmtp*********************: Removing members in parallel')
  await Promise.all([
    alixGroup.removeMembers([new_one.address]),
    alixGroup.removeMembers([new_two.address])
  ])

Test code here is causing a fork due to client processing their own message as an external message. Database locked is showing in the logs, likely cause

A variation on this we'll want to test as well is what happens if the two removes happen in parallel, but are being done by different group members. That can happen in the real world as well (me and you both kick someone out of the group at the same time right after an installation was revoked)
