'Consortiums' should be nil since system channel is no longer supported in Fabric v3.x

Description

I was running the devmode setup and the following warning appeared:
'Consortiums' should be nil since system channel is no longer supported in Fabric v3.x
I guess it should be fixed, as the main branch contains already pre v3.x stuff? If its safe to just remove the consortium entry, I'll be happy to do it.

Steps to reproduce

$ configtxgen -profile SampleDevModeSolo -channelID syschannel -outputBlock genesisblock -configPath $FABRIC_CFG_PATH -outputBlock "$(pwd)/sampleconfig/genesisblock"

which fabric sample did you use? the configtx.yaml there should not have the Consortiums
