Lockbox cannot correctly load a GitHub Remote dependency when the repo name is not the same as the package name

[peterhurford]

Only happens really rarely, but some R packages (like roxygen2) have a different package name than their repo name. Since we avoid making a call to find the package name, we end up with false positives.

This is not urgent, but we may want to consider fixing eventually.

I think this may also be true for Devtools remotes.
