[gnome-notes/136-implement-the-list-row-pattern-in-main-view: 4/8] list-view: make list-view-row responsible

[Isaque Galdino de Araujo <igaldino src gnome org>]

commit 8c38db2615ce4ec187a0311744fe16851cd7cf4d
Author: Isaque Galdino <igaldino gmail com>
Date:   Sun Jun 14 23:33:19 2020 -0300

    list-view: make list-view-row responsible
    
    With this change, BjbListView hands over BjbListViewRow information
    ownership to BjbListViewRow itself, which makes more sense.
