Seg-fault when deleting model with gazebo_ros_gpu_laser

When test-driving the example robots in the tunnels, I spawn them with subt_example team.launch and then delete a few of them to speed up the simulation. I've noticed that gazebo seg-faults when I delete a model that has a gazebo_ros_gpu_laser plugin. I collected a backtrace after installing gazebo and gazebo-ros debug symbols and uploaded it to the following gist:

• changed priority from "major" to "minor"

Moving this to minor since we don't expect teams to delete models.

• changed state from "new" to "wontfix"

We won't fix this issue because teams don't need to delete models, and we will switch to Ignition Acropolis in Feb 2019.
