Creation of deploy-tag fails if local repo does not have the deployed commit #18
Description
Capistrano creates the deploy tags on the local repo and then pushes the tags to the remote.
If the commit that should be deployed does not exist in the local repo, the deployment tag cannot be created, because the commit has cannot be found.
