Effect type inference error on typescript 4.9

[otaviosoares]

Type inference for effects fails when payload and rootState are optional. It can be observed in here:

rematch/packages/core/test/ts_typings/dispatcher-typings.test.ts

Lines 338 to 339 in bde199f

	dispatch.count.incrementEffect(2)
	dispatch.count.incrementEffect()

To Reproduce

Use typescript 4.9+

Expected behavior

I should correctly infer the effect type.

Additional context

Not sure if this is a rematch or typescript bug. I was debugged the types in rematch and tracked it down to type ExtractRematchDispatcherFromEffect on this line

rematch/packages/core/src/types.ts

Line 576 in bde199f

> = TEffect extends (...args: infer TRest) => infer TReturn

The effect function with optional args is not matching (...args: infer TRest) so it infers to never.
