Disable serialization for custom errors on renderer middleware

When a redux thunk rejects with a custom error, redux prints a warning on the console because it's not able to serialize-deserialize it. For example:

```js
return rejectWithValue(new ProjectError('INVALID_PATH'));
```

Warning/Error:

The warning doesn't have any side effects, as the errors can be handled anyway, but disabling this warning with `{ serializableCheck: true }` is not a good solution.

A possible solution is to modify the middleware to hande custom errors (errors that extend from BaseError) without trying to serialize them, but keep serialization on all the other values.
