[lifecycle hooks] Make afterAll hooks operate in the fashion as after…

…Each. (jestjs#3275)

It was discovered that afterAll hooks run in the same order that you add them,
while afterEach hooks were running in reverse order.  This commit makes their
order consistent, and adds regression tests.

Relevant issue - jestjs#3268
