Subgraph: added SortitionModule to data sources

[tractorss]

1. Added sortitionModule as dataSource to subgraph
2. updated the UpdateJurorStake function to use SortitionModule as contract , since getJurorBalance is now a function in SortitionModule.
3. Updated the events and handlers, StakeSet. ,etc now handled in ./src/SortitionModule.ts
4. Tried to test locally , but local stack fails, upon calling "yarn simulate:local" in contracts directory the command fails due to "ArbitrationExampleEthFee" not existing as the contract is not in the arbitration/examples.
5. Trying to test the subgraph with "yarn test" but thats running into errors too.
