apollo service:check is not considering the commitId nor author params

**Intended outcome:**

**Actual outcome:**

**How to reproduce the issue:**
On any machine try to check the schema with `branch`, `author` and `commitId` params like bellow:
`apollo service:check --key=... --localSchemaFile=schema.graphql --commitId=33aaf0ad280f2f0214a287bb0e1a3a959cfd2461 --author="Mike Shinoda " --branch=feature-branch-name --variant=current`

Docs: https://github.com/apollographql/apollo-tooling#apollo-servicecheck

From those 3 params mentioned above, only `branch` is actually set on Apollo Studio, the `commitId` and `author` params are ignored.

I tried to explorer myself to understand what was causing the issue and I found out this was introduced on this PR: https://github.com/apollographql/apollo-tooling/pull/2156

**Versions**
- apollo/2.32.10
- darwin-x64
- node-v12.13.1

Start at the `apollo service:check` command and inspect PR #2156, which the report identifies as the likely source of the regression. Reproduce the command with `branch`, `author`, and `commitId`, then verify that all three values are sent to and recorded by Apollo Studio rather than only `branch`.
