Zero Values for Assigned Mem (MB) in Topology Summary and Used Mem (MB) in Supervisor Summary

We have recently built storm 2.3.0-SNAPSHOT from git with commit hash 4a1eea700766da2f175ac7eaba6064f0d7f0ff03 because we needed the bugfix in STORM-3652.

It seems in this built information about the sum of the used memory is lost (it was working before in 2.2.0, release version). Individual topologies/components still get their memory assignment displayed, but the total is missing. This affects the root view (index.html) of the UI, where information is missing in the supervisor section (displayed value for used mem is zero), as well as the topology view (topology.html, displayed value for assigned mem in topology summary is zero).
