Fix the Thresh Q-Vayne Q interaction please

The interaction between Thresh's hook and Vayne's tumble is so broken. If Vayne tumbles away from a thresh hook, if the hook hits the start point of the tumble, Vayne will be hooked. You can clearly see that the hook did not hit the actual Vayne model as the hook model will have to curve to actually look like it's 'latched on' to the vayne model.

Here is evidence of it (not my vid but meh :P): https://www.youtube.com/watch?v=IsyJcdaZn_Q&feature=youtu.be
