original() causes a typescript error

[tmtron]

🐛 Bug Report

Link to repro

Stackblitz example

To Reproduce

use the example code from the immer original docs with typescript

const baseState = {users: [{name: "Richie"}]}
const nextState = produce(baseState, draftState => {
	original(draftState.users) // is === baseState.users
}) 

Observed behavior

When using the original() function as described in the docs, we get a typescript error:

Argument of type '{ name: string; }[]' is not assignable to parameter of type 'Drafted<{ name: string; }[], ImmerState>'.
  Property '[DRAFT_STATE]' is missing in type '{ name: string; }[]' but required in type '{ [DRAFT_STATE]: ImmerState; }'.

Expected behavior

No typescript errors

Workaround

cast to any:

	original(draftState.users as any) // is === baseState.users

Environments

• IntelliJ with typescript 3.4.5
• Stackblitz example

• Immer version:
• Occurs with setUseProxies(true)
• Occurs with setUseProxies(false) (ES5 only)

This is a regression indeed, will be fixed in 5.3 through #506

Thanks, that was fast!
just updated to 5.3.0 and can confirm that this works now.
