persistent-nodemap: use the intended uuid size
I overlooked this in the initial implementation. The format already supporting
any uuid size so, nothing horrible should happens.

Check upgrade behavior
======================
Right now, sidedata has not upgrade support
Check that we can upgrade to sidedata
