chore(server): Remove import sleep and pending function

Removes import sleep and pending function.

This just seems like a style change and maybe we don't need this? Not sure what the exact motivation is here.

@LucioFranco The motivation is refactoring. In general, importing functions directly is avoided as it reduces readability. In particular, in this case there is a sleep variable in the file, and since these used only once in this file, having the full path to it in the place where it is used improves readability.

@tottoto that makes sense, would be good to include a short version of those motivations in the future for things like this. 😄

@LucioFranco I think this motivation is sufficiently obvious, but it is possible you want some explanation as this case. It is very difficult to decide what should be explained in advance. I think it would be good if that could be clarified during the discussion in each case. I think it is good to ask it when having some question.
