fix(tests): Add missing http_addr field to NetworkConfig in tests

Added http_addr field to test configurations after it was added to
NetworkConfig for REST API support. This fixes Nix build failures
during test compilation.

Files fixed:
- chainfire integration tests (3 occurrences)
- plasmavmc grpc smoke test (1 occurrence)
