test_runner: fix ordering of test hooks

For tests with subtests the before hook was being run after the
beforeEach hook, which is the opposite to test suites and expectations.

Also, a function was being used to close over the after hooks, but at
the point it was being run the after hooks were not yet set up.

Fixes #47915
