Tests that a fully signed transaction given to
signrawtransactionwithwallet is both unchanged and marked as complete.
This tests for a regression in 0.20 where the transaction would not be
marked as complete.

as the feeRate argument should soon be deprecated.
Also loosen one test (and a similar one) that caused a one-off CI failure with:
expected message
'Insufficient total fee 0.00000141, must be at least 0.00001704 (oldFee 0.00000999 + incrementalFee 0.00000705)'
actual message
'Insufficient total fee 0.00000141, must be at least 0.00001712 (oldFee 0.00001007 + incrementalFee 0.00000705)'

A check to raise an error on zero-fee txns was mistakenly extended in commit
a0d4957 from the bumpfee and send{toaddress, many} RPCs to also include
fundrawtransaction and walletcreatefundedpsbt.
This commit overrides zero fee rate checking for these two RPCs, not only for
the feeRate (BTC/kvB) arg to return to previous behavior, but also for the new
fee_rate (sat/vB) arg.
