Minion/Monster damage shouldn't inturrupt Quinn's ult channel

This one issue has really been bugging me since Quinn's rework first hit the PBE. For those who don't know, Quinn's 2 second ult channel is interrupted by all damage, including minions and monsters. Wasting 100 mana and precious seconds because a caster minion suddenly decided it wanted to attack you is quite frustrating.

Having the channel cancelled due to a random caster minion suddenly deciding to attack you is frustrating and doesn't really add much in terms of gameplay. It's too rare to justify walking away, but happens often enough to be frustrating when you waste time.

Quinn already gets punished for trying to ult in the middle of a minion wave;

1. Damage from the minions
2. The enemy team knows you've ulted and where you're going
3. Tag Team's movespeed boost doesn't apply when you're damaged by minions.

Rek'Sai has a similar hyper-mobility channel ultimate, but her Void Rush is not interrupted by minion or monster damage.

Making it so that minions and monsters don't interrupt the channel barely affects Quinn's power budget while saving players a lot of frustration. There's no need to punish Quinn so heavily for using her already gated ultimate.
