Otherwise we can end up double counting txs towards the weight,
which can over-state the pool weight. E.g. relay tx to node in
stem phase, add its weight to pool weight, then receive tx
from another node, then bump the pool weight again. That double
counts the tx towards the pool weight.
If the weight exceeds the max, the node will "prune" txs from the
pool. Thus, over-counting is probably a cause of, but perhaps
not the only cause of:

- Make sure to mark identified spends in the pool as spends. The
wallet might not know these have been spent if it wasn't the wallet
that relayed the tx to the daemon, or the wallet was cleared via
rescan_bc.
- Make sure to add spends to m_unconfirmed_txs if not present.
- Make sure to process the entire pool again if refreshing for
the first time. The wallet fetches pool and blocks at the same
time. The wallet scans blocks first, then pool. If the wallet
identifies received outputs in the chain, then it may have spent
those received outputs in the pool. So we make sure to re-process
the entire pool again after scanning the chain for the first time.
- Multisig wallets that know about spent key images can now detect
spend txs in the pool. Update tests for that.

A reorg can end up causing an output's position in the chain to
move. Since the wallet doesn't update the RingDB on reorg, it
may refer to the output's stale position in the chain.
This seems a reasonable solution rather than introducing complex
logic to update the stale ring member's value on rerog, since
RingDB can be deprecated with FCMP++.
Bug was introduced in c069c04ede, before this txpool additions were not notified on block addition
When receiving blocks with previously unknown conditions, miner data was sent first, but txpool add events for already-added transactions in previous block were sent afterward. Miners would then include already-mined transactions in their new templates due to receiving the mistimed txpool add event.
The fix is to send miner notifications AFTER txpool events are sent, and before normal block notifications are sent (for mining switch speed purposes)
