test: Fix test on initrd

This was broken since I first introduced the test on initrd on
40ffc51 ("Initial parsing of the provided initrd file") but it
always was as a work in progress test.

Now that the initrd parsing has separation of concerns with the global
'tasks' variable since f4986da ("Accept tasks as a parameter on
initrd extraction"), we can have a proper test written for this.
