This fixes the ability of the remote-ls command to take a file:// URI
instead of a remote name, which is especially useful for repos on USB
drives (created via `ostree create-usb`) which are temporary and don't
warrant being added to the repo config. This commit also updates
relevant documentation, adds a unit test, and updates a few variable
names to improve readability.
I can't find a commit in the history where this was working, but it's
working on the Endless fork of flatpak so I think there was agreement at
some point that it's desired behavior.
