fix(view): fix non-registry specs

This was working by coincidence in 7.7.6 and before, and broken in the
7.8.0 refactor.  Before, it would see there was no "name" in the spec,
and then read your local package.json, and from that get a `latest`
tag.  So, if you didn't have a package.json in your CWD it would fail
with an ENOENT trying to read it.

This fixes it for real, so that if you aren't asking for info from a
registry spec, it goes ahead and looks for the `latest` tag (or whatever
tag you have configured as your default).
