Merge UC92 into Master

We have created UC92 and added significant tests to ensure the compliance of it's functionality. Please run the tests locally, merge the branch locally with master, run the tests and if they pass, please approve this merge request.

To run the tests, do the following:

1. First, run mvn install -DskipTests to build and deploy the website (this will ensure that the selenium tests work as expected)
2. Then run the following commands:

mvn test -Dtest=ActivatePatientTest
mvn test -Dtest=DeactivatePatientTest
mvn test -Dtest=ViewAllPreregisteredPatientsTest
mvn test -Dtest=ActivatePatientActionTest
mvn test -Dtest=DeactivatePatientActionTest
mvn test -Dtest=ViewPreRegisteredPatientListActionTest
mvn test -Dtest=GetRoleTest
