Error when using redux-api-middleware v3

Hello,

I'm trying to implement this library, but since v3 of redux-api-middleware remove the CALL_API alias, I'm getting the following error:

> Unhandled promise rejection TypeError: Cannot read property 'endpoint' of undefined
> at **defaultIsRefreshCall**

checking the code, I found the line that is giving the error:

```
const defaultIsRefreshCall = (action, refreshAction) => {
return action["Call API"].endpoint === refreshAction["Call API"].endpoint;
};
```

I'm guessing because explicitly is expecting for CALL_API on the action, but since now the alias is RSAA nothing is found.

is there any plan to upgrade this library to work with redux-api-middleware v3 an RSAA alias? or is there a work around I can try?

thanks in advance for your help.

Start by tracing the reported defaultIsRefreshCall function and how actions are passed to it when using redux-api-middleware v3. Verify the RSAA action shape and the refresh path; done means the middleware no longer throws when CALL_API is absent and works with the v3 alias.
