AttributeError: 'Host' object has no attribute 'name' in _on_error_event

I've just seen this:

error caught in notification handler 'b'nvim_error_event' [0, b'Vim(sign):E158: Invalid buffer name: 12']'
Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/pynvim/plugin/host.py", line 139, in _on_notification

I guess that self.name = name is needed in _load. Or (seems more likely) _on_error_event should get the client name a different way, instead of expecting that attribute on the host object.
