If one task for whatever reason is executed twice the callback is never triggered because the chord will be deleted before the last task is executed. The last task will then raise a warning that the chord can't be found.

This makes sense, you could consider refrasing the warning so it indicates why it's emitted instead of what broke. Something like "Chord %s executed more tasks than expected"

The tests seem to be wrong. The counter goes to 0 but the group was not done.

I don't think this is correct, we have a header of 2, 1 is done, the other fails.
If a task in the header fails the chord is done and the callback is not called.

If this is the case, a ChordCounter object will remain in the db for every failed chord.
