spdx-satisfies crashes for some license identifiers

[Jinwoo Lee]

I found a few spdx license identifiers that make spdx-satisfies crash: TCP-wrappers, Unicode-DFS-2015, Unicode-DFS-2016. They are all valid IDs both in https://spdx.org/licenses/ and https://github.com/shinnn/spdx-license-ids/blob/master/index.json.

The same for Unicode-DFS-2015, Unicode-DFS-2016. I'm not sure there are more such IDs.
