feat: Propagate errors thrown in afterAll blocks

If an error is thrown in an afterAll block, it needs to be handled
specially since the error isn't attached to a specific spec.  This
change won't fail any specific test, but will cause a general failure
which will still cause overall run failure.

Closes karma-runner#161
