cosmiconfig: Version 2.2.0 and 2.2.2 break webpack build (Module build failed: TypeError: Invalid PostCSS Plugin found: [0])

Hello,

On previous week you have released version 2.2.0 which breaks our webpack build. Your revert in 2.2.1 fixed our problem but today I see that you publish version 2.2.2 which again breaks build.
