[Cashtab] [airdrop chronik for mint address p1] Get minting address with chronik and compare to bch-api result

Summary:
T2730

This is part 1 of a stacked diff to remove a bch-api call from Airdrop.js

In this part, chronik is used to calculate the same information (i.e. the minting address). A console.log statement confirms that both methods get the same result.

The rest of this stack will deprecate the bch-api approach and remove debug logging.

Test Plan:
npm start
Create an aidrop tx and hit the switch for 'Ignore eToken minter address', hit 'Calculate Airdrop' button
Observe the dev console for Chronik and bch-api got the same minting address statement
Confirm you get the same result for a handful of different token ids
