Fixed a bug with the client-called walk+skill chain,

When you trying to cast a skill on a target while you are out of the skill range you use,
BEFORE: you'd walk to the target until you reach the skill range
NOW: you move to the target until you reach the skill range and automatically use it (official behavior)
