When losing the Ensnare spell while a net is currently flying towards its target, it will have no effect on the target at all on impact. The spell does nothing.

Repro:
1. Acquire Ensnare with Doom
2. Wait for the creep to be digested
3. Find another neutral creep with different spells
4. Cast Ensnare on an enemy
5. While the projectile still flies, devour the neutral creep to gain new spells

Result: Once the Ensnare spell is lost, the already launched projectile stops working, doing nothing on impact.

Expected: Already cast instances of spells should continue to work, regardless of whether the spell is still available or not.

Note: This works fine for Rubick. When he steals a new spell after throwing the net, his net still works normally on impact, even after losing the spell
