uri has not joined space

[freesig]

There's a new error showing up in sim2h that could be a regression.

When tracing I found the paths that lead to this error are in the direct message task and these are the two messages that produced the error locally on my machine:
1.

  "type": "string",
  "value":

Some(EncodedSpanContext([218, 70, 49, 138, 152, 185, 117, 227, 6, 6, 77, 247, 111, 142, 196, 52, 66, 3, 243, 160, 76, 188, 75, 233, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0]))))"
}

}

This was produced with a simple direct message stress test with just two instances.

It looks like there is a race condition between Store::new_connection() and Store::get_space_info_from_uri()

[freesig]

The self.spaces gets cloned before it's updated by new_connection

[freesig]

So I'm fairly confident this is a race issue with when the sim2h_handles state get's cloned.
If you put a 2 second sleep here

holochain-rust/crates/sim2h/src/lib.rs

Line 284 in 5595444

then the error doesn't show up.

So basically this error happens when sim2h is running fast not slow.
