Subject: node-proxy: do not fail when empty data is received
X-Git-Tag: v19.2.1~323^2~1

node-proxy: do not fail when empty data is received

If for some reason the redfish returns empty data, node-proxy fails
because it can't access non-existing keys in `_sys` dict.
It basically throws a KeyError exception.
