Patch 967ebacaa4 (view_update_generator: Move abort kicking to
do_abort()) moved unplugging v.u.g from database from .stop() to
.do_abort(). The latter call happens very early on stop -- once scylla
receives SIGINT. However, database may still need v.u.g. plugged to
flush views.
This patch moves unplug to later, namely to .stop() method of v.u.g.
which happens after database is drained and should no longer continue
view updates.
