Added Selenium tests for different combinations of selections on screen, as well as error scenarios.

Updated testFilterByGender unit test to reflect the addition of three dead female patients. The test was failing as female patients went from 24 to 27.

Updated patients 1-8 to add death date and cause of death data. Also updated TestDataGenerator class to omit calling deadPatient methods as they were causing log-in issues.

uploaded deadPatient sql files, updated TestDataGenerator and CauseOfDeathTrendsReportTest.java test file
