fix: fall back to conventional commit-parser settings for missing keys (

#496)

* fix: fall back to conventional commit-parser settings for missing keys

BREAKING CHANGE
This potentially changes implicit commitlint behaviour users may
have relied on in earlier versions. Instead of falling back to the
builtin commit-parser defaults we now default all keys to
conventional-changelog-angular.

* test: add case for #399

* chore: update yarn.lock

* test: sort result lists
