[Gameplay] Camille's ult gets cancelled but set on cooldown if target goes invisible

Spotted during a poro king game, wether you're up against a shaco or the enemy simply uses your ult is cancelled with absolutely no recompense, including removing your brief window of invulnerability even if the jump hasnt completed.

Needless to say its EXTREMELY frustrating to have a 140 second ultimate go on cooldown without getting any effect out of it.

Steps to reproduce: fade out of vision or become untargetable as Camille is in the air (timing doesnt matter - wether its right after she presses the button or right as she lands, her ult will still be cancelled and you're free to walk away.)

Why does this seem unreasonable? Camille's ult is so broken herp derp

This does not happen to either Jarvan IV or Fiora, champions that can both be compared to Camille in terms of ultimates. Hence it shouldnt to her, either.
