Generated rbxl files have duplicate services when loaded

[LPGhatguy]

This manifests itself mostly in Rojo -- services aren't tagged with the right piece of metadata in the binary format I don't think, which causes this fun:

Search the class name in rbx-reflection and check the tags?

[LPGhatguy]

rbx_reflection is pretty new relative to rbx_binary, but yeah, I think that's the best plan!

Looking into the details of the format from the public sources available, I actually don't see where this metadata would even go. O_o

The additional data byte (defined by this document) isn't set for instances like Lighting in the example, but I was certain that would be the cause of this bug!

EDIT: After testing this, enabling the extra data segment does fix this bug. Neat.
