update estimatesmartfee rpc to return max of estimateSmartFee, mempoolMinFee and minRelayTxFee.
This will provide better estimates which would be closer to fee paid in actual
transactions.
The test has also been changed such that when the node is restarted with a
high mempoolMinFee, the estimatesmartfee still returns a feeRate greater
than or equal to the mempoolMinFee, minRelayTxFee.(just like the feeRate of actual transactions)
