`assistant` contains the assistant plugin object that triggered the
event, but you can't create event hook conditions on attributes that are
plugins.
The event should also store a `plugin` attribute which contains the
unique plugin name, so hooks like these can be built:
```
from platypush import hook
from platypush.events.assistant import ConversationStartEvent
@when(ConversationStartEvent, plugin="assistant.google")
def on_google_conversation_start():
...
```
It wouldn't be possible to construct a hook condition like the one above
on the plugin object reported on the `assistant` attribute.
Even though `platypush.events` is just a symlink to
`platypush.message.event`, imports from those two modules will be
treated as different imports, thus hook conditions build on
`platypush.events` imports will never match.
Weird errors seem to happen on Twine on that image:
