Minecraft no longer prints an error to the game log when a model fails to define a texture

Discovered while testing MC-236295.

Relates to: MC-236295 MC-263121 MC-276750 MC-276751 MC-276813

The bug

In prior versions of the game (circa 1.17), defining a texture in models but not pointing it to an existing model file would cause warnings to be displayed in the game log:

Unable to resolve texture reference: #texture in [PATH TO MODEL]

As of more recent versions of the game, this no longer happens, but the missing texture still appears.

How to reproduce

A resource pack that makes sandstone point to unresolved textures is attached to this ticket.

Expected results

Applying this resource pack would display related errors in the game log.

Actual results

It does not.
