Adding some test coverage

[jmaslek]

Not sure how far I will get before I head out but will update here

• Our formatting tests were failing because futures called tickers instead of symbols so I changed that
• Adding unit tests on economy macro -- which will help with making sure the csv countries are kept (note economy controller coverage was 48%). is now 54.
• Added unit tests on fred from controller
• Unit test on call index. Up to 65%
• Unit test on call_treasury. 72% coverage on controller
