Make api.save/load work with numbers rather than {value: number}

[christianchown]

Hello - running the example as is gives an error on loading.

api.save(...) gets passed a number:

redux-loop-ts-example/src/reducers/index.ts

Lines 43 to 47 in 00cc41c

	Cmd.run(api.save, {
	successActionCreator: actions.saveCountSuccess,
	failActionCreator: actions.saveCountError,
	args: [action.value],
	})

redux-loop-ts-example/src/actions/index.ts

Lines 46 to 51 in 00cc41c

	export function saveCount(value: number): Action {
	return {
	type: SAVE_COUNT,
	value,
	};
	}

but expects a Counter:

redux-loop-ts-example/src/api.ts

Lines 30 to 34 in 00cc41c

	save: (counter: Counter): Promise<null> =>
	flakify(() => {
	localStorage.setItem('__counterValue', counter.value.toString());
	return null;
	}),

Similarly, api.load() resolves a Counter:

redux-loop-ts-example/src/api.ts

Lines 35 to 44 in 00cc41c

	load: (): Promise<Counter> =>
	flakify(() => {
	const storedValue = parseInt(
	localStorage.getItem('__counterValue') || '',
	10
	);
	return {
	value: storedValue || 0,
	};
	}),

but the action expects a number:

redux-loop-ts-example/src/actions/index.ts

Lines 72 to 77 in 00cc41c

	export function loadCountSuccess(value: number): Action {
	return {
	type: LOAD_COUNT_SUCCESS,
	value,
	};
	}

This then leads to the state shape being wrong, and the element refusing to render (Objects are not valid React children).

This commit gets rid of Counter and has the api just deal with numbers.
