Eth Mainnet shows 2 Dai by default If the user is not logged in to MetaMask or Nifty Wallet

Issue
Affected only on https://dai-bridge.poa.network/ not http://bridge.poa.net

ETH Mainnet shows my balance to be 2 Dai, however I am not logged in. It should show 0 Dai.

I saw similar issue during testing with other networks. Could it relate that some value from the browser storage are used?

The issue is produced by making the call to get the token balance of the user even if user is not logged in, so we need to fix this. In this case, since we don't have the user account, it's making the call with an empty address. It turns out that 0x0000000000000000000000000000000000000000 address has a balance of 2 Dai.
