Be able to test both fixed-asset and fixed-asset-base in a build

[davidkel]

Currrently fixed-asset-base isn't tested by the build as the benchmarks specify a chaincode of fixed-asset which could test fixed-asset or fixed-asset-base.

The way to solve this would be to upgrade the chaincode from one to the other and re-run the tests

./network.sh deployCC -ccn fixed-asset -ccp ../../caliper-benchmarks/src/fabric/api/fixed-asset-base/go -ccl go -cccg ../../caliper-benchmarks/src/fabric/api/fixed-asset-base/collections-config.json -ccv 1.0.1 -ccs 2

Or we can run each of the chaincodes and languages as individual build runs but that will result in longer runs because of each VM needing to setup testnetwork
