Debug Assert in UdderSystem

[slarticodefast]

Description

It looks like it fails to resolve the solution container when an entity with UdderComponent is outside PVS range.
Likely introduced in #32905 which moved UdderSystem to shared.

Exception has occurred: CLR/Robust.Shared.Utility.DebugAssertException
An unhandled exception of type 'Robust.Shared.Utility.DebugAssertException' occurred in Robust.Shared.dll

Reproduction

• spawn a cow
• walk away until it leaves PVS range
• get a debug assert
