Go back to original window after code action execution

[dodomorandi]

This is a pretty simple change that should fix the minor issue related to the cursor jumping to the first window containing the current buffer instead of the last last window.

@PPakalns could you confirm the fix for the issue? Thank you!

Closes #363

@dodomorandi I'm seeing the same issue, and your branch fixes it for me :+1:

Just tried this fix out as well and it works great for me too!
