fix(areachart): fix misaligned rendering props (#141)

There was a misalignment between the animated props and the non animated ones that causes the area line to use the fill instead of stroke wrongly rendering the line on the chart. We also aligned the animated and not animated props for line and bars. 
React Spring also distributes ES6 by default, which breaks jest tests unless it's imported explicitly
using the cjs extension. see pmndrs/react-spring#555

fix #140
