Keep a have held by an interrupted backup and naming nothing out of the node's own

novox's postgres stayed held after mesh-host #189: its have, written before that fix,
names no build, so the node's own composition still took it in and was refused for its
secret reader before the start could back it up again. Only that exact record leaves
the node's own; every other have naming nothing keeps main's rule. Completes #189 for a
have written before it (issue 1289).
