// useage of screating asyncAction
// first argument is Promise provider - it needs to return some promise that will be resolved
// 2nd argument is function that will change the state. This function is called 2 times - 1. when action is called, 2. when promise is resolved or rejected
// 1st argument of this function is current state and 2nd argument is data in a form:
// {loading: true/false, data: undefined/promiseResult, error: false/promiseError}
