Crash when calling WorldControl service over model with AckermannSteering plugin

[gzfuzz]

Environment

• OS Version: Ubuntu 22.04
• Source or binary build?
  source build
  gz-sim version: 5641ef2
  built with
  gcc version: 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04)
  build options: -DCMAKE_BUILD_TYPE=Coverage

Description

• Expected behavior: Gazebo doesn't crash
• Actual behavior: Gazebo crashes

Steps to reproduce

1. gz sim a.txt -r

2. dynamically creating a model with AckermannSteering plugin:

gz service --timeout 10000 -s /world/world_0/create --reptype gz.msgs.Boolean --reqtype gz.msgs.EntityFactory --req 'sdf: "<sdf version=\"1.11\"><model name=\"vehicle_blue\">\n      <pose>0 2 0.325 0
