Do not create wirebox with empty AABB (ogre)

[iche033]

🦟 Bug fix

Fixes #1000

Summary

Prevent creating a wirebox with empty AABB in ogre.

A gz::math::AxisAlignedBox initializes the bounds to MAX_D and LOW_D which results in an inf AABB in ogre as it uses floats for AABB instead of doubles. This then leads to a crash when ogre tries to render the scene.

See #1000 for a description on how to reproduce the crash with gz-sim. You can launch gazebo with ogre render engine by running:

gz sim -v 4 shapes.sdf  --render-engine ogre

Expand the sun item in the Entity Tree and click on sunVisual to see the crash.

The changes in this PR only prevent the crash - it does not actually display the wirebox for the light visual, which is the same as the original behavior.
