Finished coding and testing SQLiteReservationsDAO

Ok, so I **love** that you're unit testing this, but this really doesn't do anything.

First, none of these tests should have `throws Exception`, because that means that the error will be passed up the call stack. Instead, use a try/catch, and if it hits the catch block, just do `fail()` because that means something went wrong and there's a problem.

Next, you should actully construct a flight like you will get them in and see if it stores it without error. For this test that will be sufficient (unless you wanted to test and see if it stored it correctly by getting that flight from the DB and doing `assert(testDao.getFlightById(whateverTheFlightIdIs).equals(flight);`, so then you actually check it with what you put into the DB
