Doublecheck that the turing warning "link" doesn't affect results or performance

[jlperla]

See TuringLang/DynamicPPL.jl#422

The question is whether the

┌ Warning: [DynamicPPL] attempt to link a linked vi
└ @ DynamicPPL C:\Users\jesse\.julia\packages\DynamicPPL\1qg3U\src\varinfo.jl:821

warnings actually matter. We should:

• Make sure we can replicate that issue happing with rbc_joint_1 or something like that. If not, we can revisit the strategy.
• Witth the current main branch do an estimate of rbc_joint_1 and rbc_kalman_1 with the burnin initial conditions we saved, for 1000 draws or something like that
• With the latest ssgu branch, do an ]instantiat and then redo the experiments. If the estimates and the ESS/s are roughly comparable then that is good enough. Confirm that there is at least one of those warnings popping up.
