Can't specify changeAction with LocalForm

[lydia-schow]

The Problem

Similar to #890, except I can't add middleware because I'm using LocalForms.

Steps to Reproduce

1. Create a <LocalForm />

2. Try to specify changeAction on a <Control /> component.

Expected Behavior

Application compiles

Actual Behavior

Unhandled Rejection (Error): Actions must be plain objects. Use custom middleware for async actions.
