Wallet Connect hangs for pre-Vaults chain upgrade created wallets that didn't make a transaction

[otoole-brendan]

Describe the bug

Wallet Connect hangs for wallets that were created before mainnet 1b/vaults chain upgrade that had not yet completed a PSM transaction.

From initial investigation into some offending wallets - it appeared that path exists to vstorage but the data is empty

This is likely affecting a number of wallets - we need to determine what the cause is, how to rectify and impact (# of wallets it affects by querying # of wallets in this state).

The user was able to connect the wallet to the PSM app, do a PSM txn, and then proceed to connect to the Vaults ui.
