[FAB-4238] install chaincode e2e test

When we call install-chaincode.js in e2e directory,
if the chaincode installation failed in peers of org1,
the test will stop and not try to install on org2.
But it still shows 'Successfully installed chaincode
in peers of organization "org2"' which is confusing.
