Add migration notification for users with Sai (#7450)

Maker has upgraded its Dai token to "Multi-Collateral Dai" (MCD) and requires all users interacting with Dai migrate their tokens to the new version. Dai now exclusively refers to Multi-Collateral Dai and what was previouly called Dai is now Sai (Single Collateral Dai). In this description, Sai refers to what was (prior to the 2019-11-18) known as Dai. Dai is the _new_ token. This changeset: 1. Only affects users who had non-zero Sai at the old contract address 2. Displays a persistent notification for users with Sai 3. Updates the token symbol for users already tracking the Sai token 4. Bumps our direct and indirect eth-contract-metadata dependencies The notification copy: > A message from Maker: The new Multi-Collateral Dai token has been released. Your old tokens are now called Sai. Please upgrade your Sai tokens to the new Dai. The copy is from the Maker team.
