check-before and --dry-run

[tj57]

Restic 0.13.0 new option --dry-run has conflict with check-before: true.
Enhancement restic/restic#1542: Add --dry-run/-n option to backup command

With this config:
``etc:
initialize: false
inherit: default
backup:
source:
- /etc/
tag:
- "etc"
check-before: true`

command: resticprofile -v -n etc backup --dry-run -v got error unknown flag: --dry-run.
Without check-before works correctly.

Was too quick in closing. Should be closed when a new build is released and you verified it. Thanks for the case.
