Re: tlmgr info --list failed on forcibly removed collection

Some more info:

With `collection-metapost` forcibly uninstalled, running `tlmgr info --list
<scheme>` on `scheme-full` or `scheme-medium` both don't raise any errors.

With `url` package, one of the dependencies of `collection-latex` forcibly
uninstalled, running `tlmgr info --list collection-latex` prints an error
on missing `url` (right after "revision" field), but then still prints all
the remaining fields, including a complete `depends` field:

$ tlmgr info --list collection-latex

But the initially reported case `tlmgr info --list scheme-small` is
special: errors were printed right after the "revision", then no remaining
fields were given.

Probably this is because `scheme-small` is special: it contains a mixture
of collections and packages. `scheme-full` and `scheme-medium` both contain
collections only, and `collection-latex` contain packages only.
