I believe I figured out why no data is displayed. I also 'fixed' it. The problem is in ```onCreate()``` method, where you first launch the activity and then populate the database. It needs to be the other way around - first load data into database and then launch ```BaseballCardList``` activity. I tested it and now data is displayed and the test passes without the call on ```testClearFilter()```. Should I include this 'fix' in this pull request?
