rpc-compat: eth_createAccessList enforces accessList item storageKeys to be sorted

[pnowosie]

I encountered an issue with the rpc-compat "eth_createAccessList" test.
The test expects the result's storage keys to be sorted in ascending order.
I think the condition could be relaxed to accept keys in any order.

This is not so easy to implement, unfortunately. We don't have a facility for modifying the comparison for specific methods.
