Merge #12296: wallet: Only fee-bump non-conflicted/non-confirmed txes
faca18dcf feebumper: Use PreconditionChecks to determine bump eligibility (MarcoFalke)
718f05cab move more bumpfee prechecks to feebumper::PreconditionChecks (Gregory Sanders)
Pull request description:
This only affects the gui.
Fee-bumping of transactions that are already confirmed or are already conflicted by other transactions should not be offered by the gui.
