fix: autohooks prefix concatenation

[climba03003]

Since no core member add value to #376 (comment)
I want to move things forward to users desire behavior.

Fixes #376

As mention in last submitted PR, I believe the long term solution is refactor the code to create a single tree that contain both hook and plugin information.

I didn't provide feedback before as I had no strong opinions and have never used the library

If you think this is better, I am behind it

Yeah this looks good, I was going to merge, but this is breaking right?

Should we merge to next?

[climba03003]

Changing of test seems to indicate this is breaking, but actually not.

The new behavior is introduced in 5.8.1 and it was never tested before.
And that is the one introducing new breaking behavior (or called non-clarified behavior).

Here is just reverting to behavior to the user most expected one.
