"shots" calculation error

[haifron]

The calculation for number of shots for a weapon with a projectile that splits
(https://github.com/FAForever/spooky-db/blob/master/app/js/UnitDecorator.js#L190)
should be
shots = shots * projectileMultiplierLookup[weapon.ProjectileId];
not
shots = projectileMultiplierLookup[weapon.ProjectileId];

This would fix the niche case of the Solace, which fires multiple splitting projectiles. (It is the only unit with splitting projectiles that has MuzzleSalvoSize > 1).

At the moment:
shots = split amount

With the fix:
shots = projectiles fired per reload * split amount

PS:
Prior to #98, solace's calculation was:
shots = projectiles fired per reload.
