chore(tests): Disable full HISTORY_SERVE_WINDOW EIP-2935 Test (#2065)

Disables the longest running test in our test set that contains 8000+ blocks and takes around 30 minutes to fill.

Reasoning with the disabling of this test:
- We are basically testing a smart contract in these tests, if there's a failure in these contracts:
  - We are never going to catch it with these tests because our tests are not changing
  - It's not going to be a consensus failure because if the contract behaves in an unexpected way, all clients will still process the same EVM code
- Contract has been running in mainnet for sufficient time.
