RBF onchain of a tx that does not exists.

[Tracachang]

Issue and Steps to Reproduce

Hello,

I am using lightning core v24.02.1.

I had a force closed channel with an active HTLC, funds were sent to from bc1qca5lwlfv8qzkchcfqdryfl89szuk2n0c3x2p7vt4gst04keygkns4x68hh to my address (bc1qf7nh8pwt30nxueqekrhapa3wyz98zxu58rfl8l) and 3 days later, the HTLCe expired was sent to the same address bc1qca5lwlfv8qzkchcfqdryfl89szuk2n0c3x2p7vt4gst04keygkns4x68hh and it seems to be stuck.

Since then I see in logs that it is trying to RBF onchain a tx that does not exists non stop:

Finally I was able to find the raw transaction in the debug logs (which was never broadcasted) and manually broadcast it. After that it was RBF and included in a block.

This seems to be the reason why my logs were full of RBF on chain, increasing fees and keep trying to RBF of an "inexistant tx", simply because the first transaction was never broadcasted. It says deferring until block 837353 but that never happened.
