Fix Issue #1232 - Bug in turf-line-split

[hanneshdc]

This PR fixes #1232.

The cause of the issue is the application of turf-square to feature bounding boxes, which sometimes incorrectly results in a smaller bounding box. While this is really a bug in turf-square, the application isn't needed here. Instead, we can remove the bbox calculation completely and allow geojson-rbush to calculate it for us instead.

Hi, what's the reason for closing this PR? Was is solved in another PR?

[hanneshdc]

@kudlav not sure what happened! GitHub seems to have automatically closed it when I rebased the branch.

Have re-opened.
