[GAMEPLAY] Friendly Tahm Kench stops Caitlyn ultimate

Pretty much exactly as the title states, if an allied Tahm Kench uses devour on Caitlyn while she is ulting, then her ult will be put on cooldown. I discovered this bug when two of my allies (Tahm and Cait) were chasing down an enemy Vladimir, and when he was just about to escape, Caitlyn decided to use her ult right before Tahm used devour to gain an extra speed buff in order to catch Vladimir. Right after this happened, I saw that Caitlyn's ultimate went on cooldown (not just by the hollow bubble by her portrait, but because she also stated this as well) without actually doing damage to the Vladimir.

How to reproduce:

1. Have a Caitlyn and Tahm Kench on the same team
2. Have Caitlyn use her ultimate on an enemy champion
3. Tahm uses devour on Caitlyn just as she uses her ultimate (before the bullet is fired)

Just to clarify, Vladimir died from an auto attack just after Caitlyn was released from Tahm's stomach, so the possibility of Caitlyn's ult mistakenly being cancelled and put onto cooldown due to Vladimir's death did not occur.
