DeprecationWarning out of the box

[cassidoo]

I get a DeprecationWarning when I try to run the generator!

• Platform: MacOS
• Lorem Ipsum Generator Generator Version: Latest
• Node Version (if a Node bug): v12.16.2

Current Behavior

I get this when I run it:

(node:58672) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'trim' of undefined
    at /.npm/_npx/58672/lib/node_modules/@postlight/lorem-ipsum-generator-generator/cli.js:177:24
    at async Promise.all (index 3)
(node:58672) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:58672) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I got the same error with Node v12.14.0 on MacOS 10.15.4.
