prune --dry-run issues warm-up command

[Anthchirp]

When using hot/cold storage rustic prune --dry-run will issue warmup commands.

The Warmup request lines come from my warmup script.

Configuration file:

[repository]
repository = "rclone:rustic-cold:"
repo-hot = "rclone:rustic-hot:"
warm-up-command = "/etc/rustic/warmup.sh %id"
warm-up-wait = "48h"

[forget]
keep-within = "30d"
keep-daily = 180
keep-monthly = 18

[backup]
exclude-if-present = [".nobackup", "CACHEDIR.TAG"]
group-by = "host,label"
one-file-system = true
parent = "latest"

To make matters worse:

• --repack-cacheable-only wasn't specified, so should have been true
• the warmup requests are for treepacks, so could have been read from hot storage:
