Update componentWillMount to componentDidMount before the next major version of React Native

[jeffraux]

According to React Native 0.60:

componentWillMount is deprecated and will be removed in the next major version. Use componentDidMount instead. As a temporary workaround, you can rename to UNSAFE_componentWillMount.

See documentation here.

Edit: add link to React Native documentation
