puppetboard/app.py: Removing :func:puppetboard/report_latest (#237)

This fixes https://github.com/voxpupuli/puppetboard/issues/234

The report_latest() function was effectively deprecated when PuppetDB
introduced the latest_report_hash field in the Nodes endpoint response
format in version 3.2. With the breaking changes to PuppetDB 4.0.0
support this function can be safely removed.
