Multiple dive calls reduxForms

### Current behavior
`dive()` needs to be called 4 times in order to access the same methods normally used with `dive()`

e.g.
```javascript
const wrapper = shallow(component, {context: {store: mockStore(initalStore)}, disableLifecycleMethods}).dive()
.dive()
.dive()
.dive()
```

### Expected behavior
`dive()` should only need to be called once.

### Your environment
macOS Mojave 10.14
Node: v10.12.0
NPM: 6.4.1

#### API

- [x] shallow
- [ ] mount
- [ ] render

#### Version

| library | version
| ------------------- | -------
| enzyme | 3.9.0
| react | 16.8.3
| react-dom | 16.8.5
| react-test-renderer | 16.8.3
| adapter (below) | 1.11.2
| redux-form | 7.4.2

#### Adapter

- [x] enzyme-adapter-react-16
- [ ] enzyme-adapter-react-16.3
- [ ] enzyme-adapter-react-16.2
- [ ] enzyme-adapter-react-16.1
- [ ] enzyme-adapter-react-15
- [ ] enzyme-adapter-react-15.4
- [ ] enzyme-adapter-react-14
- [ ] enzyme-adapter-react-13
- [ ] enzyme-adapter-react-helper
- [ ] others ( )

Reproduce the reported shallow-wrapper behavior with redux-form 7.4.2, Enzyme 3.9.0, React 16.8.3, and the React 16 adapter. Compare the current four-call example with the expected single dive call; done means the same methods are accessible after one dive.
