Describe the bug
The currency logos in the finance app are not loading from the source e.g. https://chasing-coins.com/coin/logo/DAI

@john-light This is mostly likely to do with an adblocker installed locally.

Not that we should really be using icons from chasing-coins.com anymore in Finance; we should be fetching via https://github.com/aragon/aragon-ui/blob/newstyle/src/utils/web3.js#L144 instead. I've updated this issue to reflect that.

The only problem preventing this from being a drop-in replacement is our testnet tokens, since we "fake" them based on their symbols.

Fixed in https://github.com/aragon/aragon-apps/pull/1048. We now load the icons from a verified github repo (TrustWallet's).
