Fix a regression from commit abddb42d, where it could pass NULL to
g_task_get_cancellable(), triggering a critical warning. This could
happen because the lifetime of data->task is not as long as the
lifetime of the ConnectionAttempt, but the code assumed it was.
Fix the problem by keeping a strong ref to that GCancellable around
until the ConnectionAttempt is finished being destroyed.
