This PR adds a tests related to a disagreement found by the txfuzzer in devnet7 caused by underspec.
The bug can be described as a tx:
The resulting value of the previously abscent storage slot is zero, and different EL clients seemed to disagree if this storage-slot value is written into the tree. The intermediary non-zero value seems to be necessary to cause the problem since different EL clients might see that as an event produce (or not) the write into the tree.
