prune: Don't abort if time is unset for pack-to-delete

 Breaking changes:
 
 Bugs fixed:
+- prune did abort when no time was set for a pack-do-delete. This case is now handled correctly.
 
 New features:
 - New global configuration paths are available, located at /etc/rustic/*.toml or %PROGRAMDATA%/rustic/config/*.toml, depending on your platform.
@@ -13,3 +14,4 @@ New features:
 - fix: wait for password-command to successfully exit, allowing to input something into the command, and read password from stdout.
 - repoinfo: Added new options --json, --only-files, --only-index
 - Creation of new keys now enforces confirmation of entered key. This helps to prevent mistype of passwords during the initial entry
+- Check: Add check if time is set for packs-to-delete
