Fixes to dummy deployment to include emitter

[stevieraykatz]

Explanation of the solution

• There were a few issues with the dummy strategy on testnet mostly related to registrar configs. They aren't tracked here, but there were reflected on-chain as config changes and we can now successfully deposit.
• The dummy strategy contract has been updated to be less opaque and returns 1:1
• The dummy strategy task now adds the vaults to the emitter so that they can emit events

Instructions on making this work

• run yarn or yarn install to install npm dependencies

I learned a lot of good stuff getting this dummy set up. Specifically, when establishing a side chain, we need:

• setAccountsContract
• setTokenAccepted
• setNetworkParams
• setRouterAsOperator

And we also need to verify vaults and strategies upon deployment. All of this will be reflected in a larger PR: #384
