* Don't automatically delete repository files if they are present Prior to this PR Gitea would delete any repository files if they are present during creation or migration. This can in certain circumstances lead to data-loss and is slightly unpleasant. This PR provides a mechanism for Gitea to adopt repositories on creation and otherwise requires an explicit flag for deletion. PushCreate is slightly different - the create will cause adoption if that is allowed otherwise it will delete the data if that is allowed.
