Paranoid apps with two remotes

[ransombriggs]

Took a minute today to figure out why I couldn't enable paranoid on an app that has two remotes. One syntax worked (-a) but the other didn't (-r). Maybe this is expected, but I figured I'd share it just in case it's a bug:
v5.1.1:/heroku/semver.io (master)$ heroku labs:enable paranoid -r production
▸ Couldn't find that feature.
v5.1.1:/heroku/semver.io (master)$ heroku labs:enable paranoid -a semver.io
Enabling paranoid for semver.io... done
