Figure out why executing the gcloud or heroku uninstall renames the uninstall file

If the uninstall script is named "uninstall.sh" (e.g. if the NodeJS project's "./deploy/gcloud/uninstall" file was named "uninstall.sh"), the `make uninstall` command renames the "uninstall.sh" file as "uninstall.sh". It's strange that the "./deploy/aws/" and "./deploy/azure" `make uninstall` scripts didn't do the same thing... 🤔
