Error with redux 4.0.0: Type 'S' does not satisfy the constraint 'Action<any>'

Using Redux 4.0.0 some errors occur while bundling a typescript/preact/preact-redux project.

Versions I'm using:
```
preact-redux@2.0.3
redux@4.0.0"
```

The errors:
```
ERROR in [at-loader] ./node_modules/preact-redux/src/preact-redux.d.ts:19:23
TS2344: Type 'S' does not satisfy the constraint 'Action'.

ERROR in [at-loader] ./node_modules/preact-redux/src/preact-redux.d.ts:214:25
TS2344: Type 'S' does not satisfy the constraint 'Action'.
```
