Subject: [PATCH] Extend
 `test_can_write_while_reading_from_replicas_if_explicit`

- Ensure that explicit method call `connected_to` with `prevent_writes: false`
  turns off 'preventing writes' in the passed block.
- Ensure that after explicit call method call `connected_to` with `prevent_writes: false`
  'preventing writes' is retained
