cf9ed307e6 qa: blocktools enforce named args for amount (MarcoFalke) Pull request description: Since #13669 changed some signatures, I think it might be worthwhile to enforce named args for primitive types such as amounts.

"""Test spending coinbase transactions.
|
|
|
|
The coinbase transaction in block N can appear in block
|
|
N+100... so is valid in the mempool when the best block
|
|
height is N+99.
|
|
This test makes sure coinbase spends that will be mature
|
|
in the next block are accepted into the memory pool,
|
|
but less mature coinbase spends are NOT.
