Subject: [PATCH] Fix a panic when repo has no license on init cmd

Fixes #9

Previously, the `copywrite init` command retrieved a repo's license info in such a way that it accessed an invalid memory address when a repo had no current license. Additional checks now fix this condition, as well as fix another previously unhandled error in the same section of code.
