All commands need the `ai_handler` argument. The PRConfig class was missing it in the `__init__` method and so it failed with this error:
```
File "/home/vcap/app/pr_agent/agent/pr_agent.py", line 76, in handle_request
await command2class[action](pr_url, ai_handler=self.ai_handler, args=args).run()
TypeError: PRConfig.__init__() got an unexpected keyword argument 'ai_handler'
```
