@encrypt_all@ and @decrypt_all@ methods in @lib/redmine/ciphering.rb@ are expected to skip validation when saving an object. But they don't because of typo in parameter name.

It may cause a failure to run @rake db:encrypt@ or @rake db:decrypt@. You can reproduce it by running the following commands.

$ bin/rake db:fixtures:load
$ bin/rake db:encrypt
rake aborted!
Some objects could not be saved after encryption, update was rolled back.

Here is a fix:
