upgrade-vaults proposal assumes an earlier governance parameter change

[dckc]

Describe the bug

The upgrade-vaults proposal assumes at least 1 vault factory governance parameter has previously been changed (i.e. that a notifier has issued a value). On devnet, it seems this was not the case as of the Oct 16/18 vaultFactory upgrades; this left an upgrade pending. The Dec 30 ReplaceAllElectorates coreEval changed the electorate parameter, which prompted the Oct 16/18 upgrade to complete; this left the vaultFactory connected to the Dec 16/18 governance contracts.
