Builder fails to cleanup object store slugs

[Cryptophobia]

Destroying an app via Deis cli does not clean up the build slugs when app name fails to match regex.

Builder Version: 2.7.1
Storage Driver: Swift
Steps to reproduce:
deis destroy --app=my-app
kubectl logs BUILDER --namespace=deis

Only log line written is clearing the cache:
Cleaner deleting cache home/my-app/cache for app my-app

Missing the lines in code at #445

log.Info("Cleaner deleting slug %s for app %s", obj, app)

my-app had over 100 builds.

Issue is potentially the regex matching:

gitRegex, err := regexp.Compile(^/ + fmt.Sprintf(gitreceive.GitKeyPattern, app, ".{8}") + "$")

Copied from original issue: deis/builder#494

@markkwasnick can you describe the slug tarball names in your object store? they should look something like /home/jangly-tailbone:git-11241b3a.
