Capistrano::FileNotFound: Rails assets manifest file not found when using --print-config-variables option #223
Description
Steps to reproduce
Do a cold deploy (where the <app>/current path does not exist).
Deploy with cap --print-config-variables deploy
Expected behavior
The assets_manifest file should be copied from the current release_path <app>/releases/20180718040802/public/assets/.sprockets-manifest-abcd to <app>/releases/20180718040802/assets_manifest_backup/.sprockets-manifest-abcd.
See in the error trace below: ls: cannot access '/home/deploy-user/test-app/current/public/assets/.sprockets-manifest*': No such file or directory
Since the /current path does not yet exist, the backup fails. Maybe(?) the /current should not be getting used at all for the backup and instead it should be the release_path that should be used at all times?
Actual behavior
An error is thrown:
WARN Rails assets manifest file not found.
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy-user@127.0.0.1: Rails assets manifest file not found.
Caused by:

The deploy has failed with an error: Exception while executing as deploy-user@127.0.0.1: Rails assets manifest file not found.
