The transport ~failing alias got reverted

@acul71 you accidentally reverted the ~failing alias for the transport test: https://github.com/libp2p/unified-testing/commit/45f600b3297d5475d11f6ab80e0e74a6c22a2407#diff-09b1b4c786a7f13d3afcb0d4a4337a5545fbad91c111dd98259dfe4df3a9fcd3R34

Please fix this ASAP.
