Tagging an image alias by shortname

When trying to tag an alias (tag) of an image using only the shortname
and no tag, we were unable to find the image in storage.  This corrects
that issue and adds an integration test to protect against regression. I
also updated the man page per the filed issue.

While writing the integration test, I discovered that inspect could also
not find a tagged image without its :tag.
