WB-1623: Cell states don't work with anchor tags correctly [fix] (#2073)

## Summary:

There’s an issue with wb-cell that was introduced after making some layout/css
changes to the components.

Turns out that Cell states won’t be displayed as expected when the cell top node
is `display: inline`. As cells are meant to use the full-width of it’s parent
container, this PR fixes that by making the top node to always use `display: flex`.

Issue: https://khanacademy.atlassian.net/browse/WB-1623

## Test plan:

Verify that cell states are displayed as expected (hover, active change the bg
color).
