Fix Issue of thunderscope not recognizing robots when ball is not on the field

[StarrryNight]

Description of the task

When the ball is not on the field, thunderscope fails to recognize the robots and keeps printing the message:
"There are robots on the field, but no ball. It is highly likely that sensor fusion has filtered the ball out!"

Edit:
I took a quick look at sensor fusion.cpp. Turns out, the get_world function has a gate where it will only return the new world if BOTH the field and ball is present. If we initialize sensorfusion without the ball, the ball will always be a nullopt, meaning that thunderscope will never get the update world and thus the robots. Changing this gating should fix this issue.

Acceptance criteria

• Diagnose why thunderscope fails to recongie the robots (or maybe it just failed to display?)
• Fix the issue and verify the fix works in the max
