annotations deprecated, but not in right place

[timkpaine]

Contradictory errors:

plotly.graph_objs.Annotations is deprecated.
Please replace it with a list or tuple of instances of the following types
  - plotly.graph_objs.layout.Annotations

ImportError: cannot import name 'Annotations' from 'plotly.graph_objs.layout' (/usr/local/lib/python3.7/site-packages/plotly/graph_objs/layout/__init__.py)

Thanks for the report @timkpaine. Yeah, the warning above should refer to plotly.graph_objs.layout.Annotation (singular).

Fixed in #1138
