I think that we can keep this test cases which focusing on recovering allocation slack. The
update for `Allocator::recoverResources` is only used when shrinking dynamic reservations,
and the allocation slack based on those shrinked dynamic reservations are being used by some
revocable tasks.

Please refer to https://reviews.apache.org/r/42113/ and https://reviews.apache.org/r/42194/
for detail.
