[Docs] Incorrect description about dispatch method

[jonathan-roy]

Is is said in the doc that:

The first thing to know is that store.dispatch returns the value returned by the triggered action handler, so you can return a Promise in an action.

Dispatch: Dispatch an action. Returns the return value of the triggered action handler, or a Promise if multiple handlers are triggered.

It seems like actually every call to dispatch() returns a Promise even when there is only one handler which does not return a Promise.

Actual behavior is correct. We'll fix the docs later.
Thanks for your report :)
