rpm-ostree override replace --experimental --freeze --from repo=foo bar should enable repo foo

[travier]

Host system details

Latest Fedora CoreOS next.

Expected vs actual behavior

rpm-ostree override replace --experimental --freeze --from repo=foo should enable the repo foo and fetch metadata from it before trying to find a package in the repo for the override. If the repo is not enabled, the command fails.

Steps to reproduce it

Follow the steps in #3347 but skip the step manually enabling the repository. Then:

$ sudo rpm-ostree override replace --experimental --freeze --from repo=kernel-vanilla-mainline kernel
