Fix prices.usd

[jeff-dude]

SELECT
  token_id,
  blockchain,
  symbol,
  contract_address,
  decimals
FROM
  prices_native.tokens
WHERE
  contract_address != 0x0000000000000000000000000000000000000000

returns no results, therefore drops all native tokens out of prices.usd

Ah yeah contract_address can be null. Need to do DISTINCT FROM instead for these cases.

[0xRobin]

this should do the trick.
Let's verify the CI output

[jeff-dude]

sounds like you guys are on the same page for this approach. i need to get used to that function.

adding context, as users have reached out for support.

• this PR was merged, due to an issue with an optimism token address (more info in description there)
• the != approach caused all native tokens to drop out of prices.tokens, which feeds into prices.usd
• rather than the above approach, the IS DISTINCT FROM function will help us get what we need

[jeff-dude]

we have an ongoing bug in CI. for our sake here:

SELECT
  token_id,
  blockchain,
  symbol,
  contract_address,
  decimals
FROM
  prices_native.tokens
WHERE
  contract_address IS DISTINCT
FROM
  0x0000000000000000000000000000000000000000

this returns results as expected. i'm good to merge.
