allow nested thunk actions in LocalForm

[eliseev-eag]

The Problem

Hi everyone! I work in large project that uses react-redux-form. Often I want to use my custom thunk actions that use react-redux-form thunk actions (for example push or merge) under the hood with LocalForm. But dispatch in Local Form doesn't allow using nested thunk action

Steps to Reproduce

I prepared CodeSandbox example

I understand that this is an artificial example and if I used non-nested thunk actions, this would work. But often in real life I need nested actions

Click to Button in CodeSandbox example

Expected Behavior

In CodeSandbox example, after clicking on Button, form counter was increased

Actual Behavior

In CodeSandbox example, after clicking on Button, form counter wasn't increased
