Physics Interpolation - fix stale interpolation data when unhiding

Browse source 
A previous optimization prevented instances being added to the interpolation lists when hidden to save processing. This caused a regression when unhiding nodes outside of the physics tick - the interpolated transforms would be stale until the next physics tick, causing a glitch.

This PR readds instances immediately to the interpolation lists when they are unhidden, preventing this glitch.
