feat: Introduce enableAutoDestroy() helper function

[winniehell]

This introduces a new enableAutoDestroy() helper function which allows to automatically call wrapper.destroy() by passing in a custom hook function (such as afterEach).

closes #1236

@souldzin can I ask you to take a look at this?

[winniehell]

I have pushed the following changes:

• simplified the tests a little
• added a guard against calling the helper twice
• made the wrapper instances scoped inside Wrapper instead of the module to allow resetting them (for example in unit tests)

[souldzin]

Thanks for the ping and iterating on this @winniehell! Back to you ⚽

[winniehell]

It looks like we want to solve #1224 and #1135 first. 😃

Looks good, two small comments.

[dobromir-hristov]

Do you think we should document the resetAutoDestroyState? I am not sure if it makes sense for ppl to need it though 😆

[lmiller1990]

I think if we have the feature, it should be documented. Maybe a sentence or two explaining when/why it's useful?

The code seems good, no problems here 👍

[afontcu]

LGTM! 👍

Regarding documenting resetAutoDestroyState, we should do so, but I wouldn't stress it too much. Maybe just mention it in the enableAutoDestroy section?

[dobromir-hristov]

Same, just mention it exists. Maybe add them to the API docs, because I find myself search there more, than in the guides.
