[BUG] - cardano-testnet: Hydra InitTx stays forever in the mempool

[errfrom]

I'm attempting to run a Hydra Head against a cardano-testnet cluster. The InitTx, posted by the hydra-node, appears in the mempool of each cardano-node but is never included in a block and therefore is not observed by the Hydra Head participants.

cardano-node version:

cardano-node 9.2.0 - linux-x86_64 - ghc-8.10
git rev 341ea87ba3b4936188f8c2d4f09bbf1976a7926e

hydra-node version:

0.19.0-1ffe7c6b505e3f38b5546ae5e5b97de26bc70425

hydra-node logs:
