When raising generic Exception, window.on_error can't tell whether
there was a programming error or we just want to communicate with the user.

Exception: No inputs found.
This is too complicated and ugly because it relies on side
effects. What we should do instead is collapse transactions
in children nodes of QTreeView (see #6237)
If a used/reserved change address became unused/unreserved, it would not
get offered for usage by wallet until app restart.
Make the used->unused transition less likely by requiring 3 confirmations
(instead of considering even local/unconfirmed txs for 'used');
and avoid removing reserved addresses from the pool altogether.
We are now using change addresses for the channel SRK to_remote outputs
(and reserving these change addresses). (see prev commits)
Note that every channel open we initiate typically uses two change addresses:
- one for the SRK to_remote output, and
- one for the funding tx change output (assuming there is change).
- Use change addresses (instead of receive) for the static_remotekey to_remote outputs,
and reserve these to greatly reduce the chance of address-reuse
- Use change addresses (instead of receive) for LN channel sweep addresses.
Note that these atm are not getting reserved.
- also, disallow deleting last address from an imported wallet (fixes#3254, fixes#4833)
- also, set LNBackups.sweep_address lazily, as during fresh wallet creation
there are no addresses in the wallet at that point yet! see trace below.
