Peer chaincode image doesn't appear to be updated when chaincode was changed

[davidkel]

When I wipe /var/hyperledger, I need to install chaincode again and it does install the package (note this is lscc) at the same version as before, but as the docker image still exists for previous chaincodes it looks like fabric doesn't see the difference (I thought it would do so because the fingerprint is different) but it re-uses the chaincode image that already exists.

restart nodes should remove all dev-* docker images on the peer
