gasPrice and maxPriorityFeePerGas APIs - Under low traffic, {eth,kaia}_gasPrice and {eth,kaia}_maxPriorityFeePerGas return a zero-tip price despite feeHistory containing high fees

• Setup. Monitor two nodes on Kairos: one v1.0.0, another v1.0.1

  setInterval(() => console.log(
  eth.blockNumber,
  parseInt(eth.gasPrice/1e9),
  parseInt(eth.maxPriorityFeePerGas/1e9), '\t',
  eth.feeHistory(20, 'latest', [60]).reward.flat().map((n) => parseInt(parseInt(n)/1e9)), '\t',
  eth.feeHistory(20, 'latest').baseFeePerGas.map((n) => parseInt(parseInt(n)/1e9))
  ), 1000)  

• [x] Test 1. Intentionally create high-tip transactions and compare the results

• base fee is maintaining lower bound (25)

• send many txs with (maxfee = 70, maxtip = 30), filling up the feeHistory.
