fix minor npm versioning warnings

[missinglink]

When running npm install there are some warnings which could probably be easily fixed:

npm WARN deprecated [email protected]: Use String.prototype.trim() instead
npm WARN deprecated @hapi/[email protected]: Moved to 'npm install @sideway/pinpoint'
npm WARN deprecated @hapi/[email protected]: This version has been deprecated and is no longer supported or maintained
npm WARN deprecated @hapi/[email protected]: Moved to 'npm install @sideway/formula'
npm WARN deprecated @hapi/[email protected]: Moved to 'npm install @sideway/address'
npm WARN deprecated @hapi/[email protected]: This version has been deprecated and is no longer supported or maintained
npm WARN deprecated @hapi/[email protected]: Switch to 'npm install joi'
npm WARN deprecated [email protected]: Package no longer supported. Contact Support at https://www.npmjs.com/support for more info.

The last one [email protected] is not easily fixed since they changed the API significantly in the new version, but other lines like deprecated [email protected]: Use String.prototype.trim() instead should be simple.
