Bump dependencies
This bumps all the dependencies that are not related to webpack / lint.
There were just 2 issues:
- newer versions of React don't allow
withRef
, which was used in one place. Instead, we can use the more traditional pattern of bubbling up values to the owner component. - c3 defined a very small size by default for the bar chart; had to make the size more explicit in the styling code. (Will be touched again after the grouped pie charts MR gets merged)
