lerna version/publish creates duplicate versions + extra whitespace in change log

Every Git commit by Lerna after lerna publish has a duplicate version in the change log, each with 4 extra newlines that follow.

Expected Behavior

• Notes for a particular version should only appear once in a change log.
• No additional whitespace under each version.

Current Behavior

Possible Solution

No idea how to fix this, but it may be an external bug with conventional commits?

Steps to Reproduce (for bugs)

For context, I’m actually using Lerna for a single package.

.travis.yml

deploy:
  - provider: script
    script: lerna publish --yes --git-remote pub
    skip_cleanup: true
    keep_history: true
    on:
      branch: master

lerna.json

{
  "packages": ["."],
  "command": {
    "publish": {
      "allowBranch": ["master"],
      "conventionalCommits": true
    }
  },
  "version": "0.1.1"
}

package.json

  "commitlint": {
    "extends": [
      "@commitlint/config-conventional"
    ]
  },
  "config": {
    "commitizen": {
      "path": "./node_modules/cz-conventional-changelog"
    }
  },

Context

I’m automating deploys and change logs, so this is the one thing that’s just not working properly at this point.

Familiarity. It’s what I use in other projects, but those projects don’t exhibit this same issue. Rather than dick around with a separate tool until it works, I figured I’d use something I already know how to configure.

That said, I’m happy to switch to semantic-release if it fixes my issues.
