This allows to break a circular dependency between package:expect and
package:async_helper, which will simplify the support for modular tests using
package:modular_test.

This happened using APIs like `Stream.first` that set cancelOnError when
they called `Stream.listen()`. If an error is signaled, Stream internals
will call `cancel()` and wait for that future to complete before sending
the error to the resulting Future. However the `async*` implementation
class did not properly account for that possiblity, and never completed
the cancellation future in that case.
