Emit TestStepStarted event on @BeforeAll and @AfterAll hooks

[HardNorth]

Is your feature request related to a problem? Please describe. It look like @BeforeAll and @AfterAll hooks do not fire any events, at least I don't see it in the code explicitly.

This makes impossible to report them in third-party report systems. At least in a straightforward way, without hacking that with AspectJ.

Describe the solution you'd like Fire TestStepStarted event as you do for all other hooks.
