v4.4.1: packaging error

[dkuhnert]

Hi,
When packaging using rollup the build currently breaks because the module property is still set in the package.json (https://github.com/STRML/react-draggable/blob/v4.4.1/package.json#L6) but the build/module directory isn't in the npm package anymore.

My assumption is that this line should have been deleted in fa030e2

Same error here. Rollup build is broken now.

Thanks -- published 4.4.2 which fixes this.
