fix minor npm versioning warnings

[missinglink]

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

npm WARN deprecated trim@0.0.1: Use String.prototype.trim() instead
npm WARN deprecated @hapi/pinpoint@1.0.2: Moved to 'npm install @sideway/pinpoint'
npm WARN deprecated @hapi/topo@3.1.6: This version has been deprecated and is no longer supported or maintained
npm WARN deprecated @hapi/formula@1.2.0: Moved to 'npm install @sideway/formula'
npm WARN deprecated @hapi/address@2.1.4: Moved to 'npm install @sideway/address'
npm WARN deprecated @hapi/hoek@8.5.1: This version has been deprecated and is no longer supported or maintained
npm WARN deprecated @hapi/joi@16.1.8: Switch to 'npm install joi'
npm WARN deprecated elasticsearch@16.7.3: Package no longer supported. Contact Support at https://www.npmjs.com/support for more info.

The last one elasticsearch@16.7.3 is not easily fixed since they changed the API significantly in the new version, but other lines like deprecated trim@0.0.1: Use String.prototype.trim() instead should be simple.
