chore(package): update last-release-npm to 1.2.1

You can now map dist-tags onto "fallbackTags". E.g. if you want a
development channel like "next" and no version is currently published as "next"
semantic-release could fallback to "latest" to determine the new "next" version.
You can specify your mappings by adding "fallbackTags" to your
`package.json`'s "release" field.

 `semantic-release` builds upon a set of conventions to give you **fully automated, semver-compliant package publishing**. It's mostly about _commit-messages_, but you can define more _heuristics_.
