VertexLoader: Fix wrong array being used if color 1 is present but color 0 isn't

Browse Source 
This worked correctly on the JIT vertex loaders, and for the equivalent case with texture coordinates. I'm not aware of any games this affects (but libogc does mention a semi-related scenario at https://github.com/devkitPro/libogc/blob/6bc0317c7d52063c2d2b48b721520093c76432a9/gc/ogc/gx.h#L1855-L1857.)
