Description

Hi!

Trying to test my code with Jest + React Testing Library and getting the error below. Seems it's related to issue #97.

I've seen you made a fix here v0.1.8...v0.1.11#diff-545931490bc9fb7bfb72fcc1db6fbf41916a8b0b67a1ae9289c7a7df84d32424 but I noticed that after source code building process.env.NODE_ENV.toLowerCase() becoming var env="production".toLowerCase(). It means env always asserts to 'production' even in a test environment. You can check this in the latest release https://github.com/alvarotrigo/react-fullpage/releases/tag/0.1.18

To be honest I'm not familiar with Jest so I'm a bit lost here too :)
