Approve spend of an ERC20 token by another wallet. The token in question defaults to POLY if no address is supplied
Note that if the amount has already been approved, the spending approval transaction will not be added to the queue and the procedure will return
Note that the procedure will fail if the owner's token balance is less than the amount being approved. The only exception to this is when approving a POLY spend on a testnet. If that is the case, an extra transaction will be submitted to request the missing amount of tokens from the faucet
Returns: Promise‹void›
