Subject: Return only `Some(block_hash)` in CM rel. txids
X-Git-Tag: v0.0.114-beta~34^2~1

Return only `Some(block_hash)` in CM rel. txids

As of now the `Confirm::get_relevant_txids()` docs state that it won't
return any transactions for which we hadn't previously seen a
confirmation. To align its functionality a bit more with the docs, at
least for `ChannelManager`, we only return values for which we had
registered a confirmation block hash before.
