Jinx Q Switch

I noticed this bug a while back, and put in a bug report. Jinx's Q doesn't allow you to switch back to minigun if you don't have mana, even though it's supposed to cost nothing to switch. So you're just stuck with one singular rocket until you run out of mana entirely and it forces you to switch back to minigun, which kind of leaves you open and defenseless in the early game if you're low on mana.
