Troll the trolls: tasks are not grouped correctly

When I did the exercise, the tests were not shown separately by task, but as one big lump.
I looked into the test code and saw that the first test cases are missing the `[Task(..)]` attribute.

It does fit into task 1. Another option would be to move the `Permissions.Default()` method into its own task and have the enum construction as the first task, so that the currently un-attributed tests can be set to task 1.
