Update react/sort-comp rule to allow flow props before lifecyle methods
Update react/sort-comp rule to allow flow props before lifecyle methods

Summary:
The default ordering for react/sort-comp forces flow props to be after
lifecyle methods.  This change makes so that flow props can appear before
the lifecyle methods which is where we'd like them.

I have to wait to deploy D35434 before I can land this.

Test Plan:
- remove the eslint-disable react/sort-comp message from table.jsx in webapp (it has flow props at the top)
- run: ka-lint javascript/components/table-package/table.jsx
- see no errors
