fix(anvil): use default gas limit if zero

[mattsse]

Motivation

Closes #3247

Solution

use default gasLimit if block's gaslimit is 0

[gakonst]

Wait..Aurora returns u256::MAX, not zero. Is the issue in the OP that they used a wrong address for the Aurora network?

[mattsse]

while the opcode returns max the api returns 0:
