Lane cannot be styled via className anymore

[Termit1975]

Describe the bug
Before e07e4a6, I was able to give a className and the

node had the specified className. Since there is the new attribute className="react-trello-lane" this overrides what comes from current className property it was done via ...otherProps

To Reproduce
Steps to reproduce the behavior:

1. Add a className to the data of the lanes
2. Class name is not added to
   dom node

Expected behavior
The section object should include the className from otherProps as well as "react-trello-lane"
