Fix hologram net messages (setScale/setClip)

Net messages can arrive before the entity is initialised.
While there was a queue to accomodate for that, the queue was indexed by
the entity. However, since all non-existant entities become
NULL-Entities, the queue was not working.

This changes the queue to be indexed by the entity index.

Fix hologram net messages (setScale/setClip)
Fix rare hologram error

If the net message for scaling/clipping arrived in a specific period of
time, it would error. This makes sure the entity is properly initialised
before any scaling or clipping is done.
