`updateEntities` tries updating entities even if they're not in the store

[EricPoul]

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

entities

Is this a regression?

Yes

Description

Here https://github.com/ngneat/elf/blob/master/packages/entities/src/lib/update.mutation.ts#L57 a check has not been presented on whether the store contains an entity with a passed id or not. In the Akita it's there https://github.com/salesforce/akita/blob/master/packages/akita/src/lib/updateEntities.ts#L26.
Because of that it returns undefined in the updater instead of an entity or creates a new partial entity if updater is a partial object.
