setEntities([]) will not update the store

[ogix]

Which @ngneat/elf-* package(s) are the source of the bug?

entities

Is this a regression?

No

Description

I would expect that setEntities([]) would delete entities as deleteAllEntities() does. Now it seems it has no effect.
I see that this is done intentionally:

elf/packages/entities/src/lib/set.mutation.ts

Line 31 in 735ee9b

if (!entities.length) return state;

What is the reason for that?

Example:

interface Todo {
  id: number;
  label: string;
}

const { state, config } = createState(withEntities<Todo>());

const todosStore = new Store({ name: 'todos', state, config });

todosStore.pipe(selectAll()).subscribe((todos) => {
  console.log(todos);
});

todosStore.update(
  setEntities([
    { id: 1, label: 'one ' },
    { id: 2, label: 'two' },
  ])
);

todosStore.update(
  setEntities([]) // this has no effect and nothing is written to console
);
