Ghost cell generator crash

We have yet another crash in the Ghost Cell Generator. Here is how to replicate:

• 5.10.0, master (v5.10.0-RC1-334-geee29c3f), Linux, builtin server AND remote server.
• Open random_geometry_tet10_and_beam.g.16.*. Apply.
• Ghost Cell Generator. Apply.

It will crash.

I will send the dataset to Cory and Utkarsh. OK to pass to anyone at Kitware. Dataset is second_tet10_example-DoNotRelease.tar.gz

I would REALLY like to get this into 5.10.1. As always feel free to push back if needed, and we can move to 5.11. Must not slip past 5.11.

Note that builtin server, if you run merge blocks, it appears to work correctly. It still crashes remote server.

Test builtin server and remote, as they are acting different.

Replicated with a debug build. Here is the stack trace:
