L2: migrating removes point from view

[jamesacklin]

• Transferred a star on L1 targeting a metamask wallet
• Logged in via MM and accepted the point, observed urbit/bridge#965
• Did not set its network keys
• Migrated the entire point to L2, which succeeded
• Refreshed Bridge (logs out, logged back in via MM)
• Point disappeared from family view and points dropdown

Observed on Ropsten; Chrome 98 / MacOS.

(After page refresh, log out / log in)

This eventually resolves, which is scary.

Solving with UX copy for the time being.
