Invalid malleated txs are not removed from the mempool cache

[evan-forbes]

When removing malleated txs from the mempool via the mempool's Update method, if the config indicates that the the node should not keep invalid txs in the mempool cache, then it should remove those txs from the cache if they are included in a block. This is not currently occuring because the mempool cache only accepts raw txs and then hashes them itself as opposed to accepting the hashes of the txs.

	// allow invalid transactions to be re-submitted
	txmp.cache.Remove(tx)

I don't think this is causing any glaring issues at the moment, but it is effectively overriding the node operator's configuration, which we should eventually fix. To fix this, we need to add a method to the cache to remove a tx by its hash instead of the tx itself. That way we can pass the original tx's hash.
