patch: mock return for textures not found by Track method (#150)

Browse source 
as discussed in #dev-chat, the goal is to feed untracked bindless textures requests with last valid bindless textures for now, so that most games keep running despite possible visual artifacts. as Track evolves, this mock shall be dropped eventually.
