Title: Solve issues regarding WelcomeActivity

Another instance of MainActivity was created in the WelcomeActivity so after exiting, there were two Main activities running. (This could be discovered by pressing the back button from MainActivity)

Also, if the back button was pressed, the app would have returned to the MainActivity leaving the name of the user blank. Now, it exits the app.
