This fixes a bug where the gather is cancelled externally and then one of
its sub-tasks (that the gather was waiting on) finishes right between the
cancellation being queued and being executed.

This double-raise test could fail when task[0] raises and stops the gather
before task[1] raises, then task[1] is left to raise later on and spoil the
test.

The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
(previously it would only finish if the first sub-task raised)
Fixes issues #5798, #7807, #7901.
