separate token lists for testnet and mainnet

[sodofi]

Current implementation of the tokenlist includes tokens from both chainId 42220 and 44787.

This change splits the list into two different lists, one for each chainId.

This will maintain tokenlist best practice structure where each list is dedicated for a dedicated chainId.

Please review this issue before merging since changing celo.tokenlist.json can affect users calling the list as it is.

we should bump the version on the celo token list.json since items were changed. not sure if its a major since items were removed or a patch since it just fixed that they shouldnt have been there

@sodofi were you going to make the changes?
