lrauv Investigate why test fixtures go :boom: if we have more than one TEST in a single process.

Google protobuf doesn't like the way we are linking the messages in our repository. Whenever we try to run two TestFixtures in the same process the tests will segfault.

https://github.com/protocolbuffers/protobuf/issues/4126 suggests loading/unloading protobuf message shared libraries leaves bad global state behind. Perhaps we can preload them?

Hopefully eventually we can move away from custom messages then?

In general running two servers in the same test seems to be troublesome with gazebo. Dunno if its the same issue but I also had troubles trying to run two servers in the same test file in gz-sim so I have to split them in two files (here and here).

We know why this happens and it's very much core to how protobuf works. I'm inclined to close this as wont fix.
