Bug: Association error: Missing identity update

[mkysel]

Describe the bug

When running XDBG (or any other d16z capable client) we get the error:

$ cargo xdbg -b local -d generate --entity identity --amount 5
xdbg::app::generate::identity 50 errors during identity generation
xdbg::app::generate::identity 1 unique errors during identity generation
xdbg::app::generate::identity err "Association error: Missing identity update"
Error: 
   0: Error generation failed

Expected behavior

No error.

This might be caused by xmtp/xmtpd#418, or a combination of that and other causes.
