Starfall always resets 'ViewEntity' when disconnecting from a HUD

[adamnejm]

Starfall always calls SetViewEntity(nil) when disconnecting from a HUD, it's annoying when using Camera or being connected to some other HUD that actually uses SetViewEntity.

Repro:

1. Place and activate Camera
2. Place chip containing enableHud(owner(), true) (any realm)
3. Remove chip
4. View gets reset to first person
