Actual behavior

Warnings show up when using react-beautiful-dnd with React.StrictMode.

Steps to reproduce

1. Use the vertical list example as a starting point (https://codesandbox.io/s/k260nyxq9v)
2. Wrap the <App /> component in <React.StrictMode> (or go straight to the following fork: https://codesandbox.io/s/3xy8342pzp)
3. See the warnings in the Console:

Warning: Unsafe lifecycle methods were found within a strict-mode tree:

4. When using the latest version of React (16.7.0), I get additional warnings about the Legacy API (same code change as in step 3 but with I additionally update to React & ReactDOM 16.7.0 - or via this fork: https://l5o4y8xoxq.codesandbox.io/):

Warning: Legacy context API has been detected within a strict-mode tree: 
    in StrictMode

Thanks! We are currently using an older version of react-redux that uses the deprecated methods. To upgrade will be a breaking change as our react peer dependency version will change #984

We will need to do this soon
