Fix bug in license string parsing

ctrueden · ctrueden · commit cd736c70c082 · 2020-06-05T15:54:14.000-05:00
We now use colon as token divider uniformly, never slash, because
we sometimes use slash for the licenseName (specifically: "N/A").

I don't know of any case where colon appears in any of these properties.
