dx: Rename UNSAFE React's life-cycle methods on path to upgrade
Rename all the deprecated React's life-cycle methods as recommended in the guides. The idea is to set an upgrade path to completely refactor the usage of these methods and comply with the new React guidelines.
We can find more information about the deprecation warnings at https://reactjs.org/blog/2019/08/08/react-v16.9.0.html#renaming-unsafe-lifecycle-methods
