vshard/storage/init.lua:528: attempt to index local 'new_tuple' (a nil value)

Recently I found following error in my logs (in tests).

LuajitError: ...tarantool/.rocks/share/tarantool/vshard/storage/init.lua:528: attempt to index local 'new_tuple' (a nil value)

Seems sometimes new_tuple could be null in on_replace trigger for _truncate space.

tarantool> box.schema.space.create('test')
---
- engine: memtx
  before_replace: 'function: 0x0109254708'
  field_count: 0
  is_sync: false
  on_replace: 'function: 0x0109254548'
  temporary: false
  index: []
  is_local: false
  enabled: false
  name: test
  id: 512
- created
