yarn check --production is checking for presence of devDependencies

What is the current behavior?
Currently running yarn check --production is not checking for only dependencies. It's also checking devDependencies. This means that if you wanted to use yarn check during a deploy, you couldn't, it would always fail. We'd love to be able to use this on deploys.

If the current behavior is a bug, please provide the steps to reproduce.
Have some dependencies and some devDependencies specified in package.json. Manually remove one of the devDependencies from the node_modules folder. Run yarn check --production, and it will fail. It should not fail, should it?

What is the expected behavior?
For yarn to only look at the dependencies when running yarn check.

Please mention your node.js, yarn and operating system version.

Yarn doesn't have a match command.

Fixed via #2116. Notably, this line.
