Errors on TS transpilation

The following issues occur if I run npm install followed by tsc. After consulting the package-lock.json @types/mocha is shipped with graphene-pk11, see also package.json. Looks to me like this should rather be a dev dependency than a production dependency.

$ npm install

> [path]
> npm run build

> [path]
> tsc
