[Gameplay] Bandit Spell procs...

I've had a couple of games now where i feel like bandit doesn't give gold when landing spells (most notably when i have spellthief edge). AAs still provide the gold as normal, but the mastery states "... attack or spell..." haven't experimented with this on melee champion yet. steps

1. pick mastery and champion (possibly must be ranged)
2. in game purchase spellthief edge starting item
3. go to lane and land spell

i would think that i just haven't been keeping track of the cd properly, but i noticed this on my first spell hit i only got the tribute gold, not the bandit gold was playing at the time but when i thought back i feel like this happened before when i was playing another supp a few days ago
