Revert "webos-image: luna-service2=191,v3.9.0"

Revert https://g2g.palm.com/#/c/5738/ because the fixed assert
on blank category names triggered crashes in at least three
components. (See BHV-9238, BHV-9237, BHV-9229.) Also suspected
in appinstall / permissions problems such as BHV-9094, BHV-9223

This reverts commit 21c192d0a87a5a793b2ad2d80e0893eb2a0d7858.
