Fix price tokens and set up tests

[0xRobin]

There's a a bad price token currently that is producing duplicates as it's reported as the 0x000.. address. (which is used to represent native tokens in many spells)
This will remove it from tokens and set up tests to discover it.

cc: @MSilb7 the core of this is originating from tokens_optimism.erc20_bridged_mapping, can you handle this edge case there? It might be a bad emitted event?

here are 2 transactions that have caused this:

select * from optimism_ethereum.L1StandardBridge_evt_ERC20DepositInitiated
where l2Token = 0x0000000000000000000000000000000000000000

discussed on our call, good to go here. next steps:

• lets this run and refresh prices.usd
• run nft_trades_beta+
• run dex_base_trades+ (jeff to confirm that's sufficient)

this will fix rows that incorrectly joined to prices and grabbed wrong price, therefore assigning incorrect amount_usd
