devicehive-iot-framework snap fails to install if no enocean modem is avaialble

[demon-xxi]

EnOcean service fails on start if no enocean device is installed on the gateway. Unfortunately snaps installation fails if any of the services fail to tart on install. Need to refactor eocean service to wait for device and ideally gracefully handle device reconnect.

The latest version installs on RPi2 and I even got it one working with my service visible in AllJoyn explorer but does not start anymore. Also I see errors related to nvram creation:
