Update SidasAutoCarryPlugin - Shen.lua

There were some Bugs with using Shen's E:
 - When someone was casting an Ulti (Warwick, Katarina, Master Yi's W...), it was giving errors with OnProcessSpell.
 - Shen's E (CastE Function) was usable only for VIP even if the user was using Revamped or Reborn.
