Sign entities stick around weirdly if signs are removed via voxelmanip

[fluxionary]

They turn into inscrutable "white pixels":

Steps to reproduce:

1. place a sign
2. add some text
3. use voxelmanip to remove the sign (e.g. //s air)
4. the entity persists.
5. unload the area, and return
6. the entity is now a white pixel.

I'm not sure how to fix that, do you have some ideas?

[fluxionary]

Yes, should be simple, testing out the fix rn.
