unhold doesn't "Remove auto-refresh hold on all snaps"

[Nobuto Murata]

$ snap version
snap 2.61.1
snapd 2.61.1
series 16
ubuntu 24.04
kernel 6.6.0-14-generic

$ sudo snap refresh --unhold
Removed auto-refresh hold on all snaps

It states "Removed the hold on *all* snaps", but it doesn't remove a hold of a specific snap.

$ sudo snap refresh --hold hugo
General refreshes of "hugo" held indefinitely
