[FABN-886]Fix gulp docker-clean for network-e2enodecc

`gulp docker-clean` doesn’t remove Chaincode's docker containers
and images of network-e2enodecc. The script (./build/task/test.js)
runs `grep` command to search docker containers and images
containing Chaincode’s name. The current `grep` command can’t find
Chaincode named `network-e2enodecc`, which is used for the
end-to-end test of fabric-network.

This CR fixes the regular expression in the script to search
and remove the remaining containers and images.
