start() throws warning

## Expected Behavior
I don't have any warnings

## Actual Behavior
I see this
**DeprecationWarning: Calling start() is no longer necessary. It can be safely omitted.**

## Steps to Reproduce the Problem
```javascript
import { DaprServer } from '@dapr/dapr'
new DaprServer({ /* ... */ }).start()
```

`start()` **CAN'T BE OMITTED**, it doesn't start without it
