[FAB-3352] No need to initialize grpc in CSCC tests

CSCC configure_test.go leverages mocking framewrk to test CSCC
invokations, while each test initializes grpc server while not real need
for this. Current commit takes care to make tests stop initializing grpc
server and clean up the test from non relevant code.
