Subject: [PATCH] Pin the lnw scan removal with computeLatestChapter tests
 (#91)

The new export is the seam the suite addresses behaviour through: for
lightnovelworld no anchor set yields a Latest Chapter, comment-shaped
anchors included, and for novelfull the scan still returns the maximum and
ignores other series. The old lnw scan test asserted the deleted behaviour.
