We add a test that checks the rendering of the activity view and the activity
popover with activities done.
We also add a test that marks as done an activity and verify that the activity
view is updated accordingly.
And we do a correction in the test "activity menu widget: activity menu with 2
models" (assert.ok(selectContaining... was always true as an array is always
returned and [] is true in javascript).
