The Account Security store was never reset on an account switch, and
the settings page only fetches while it has no verdict yet. After a
switch it kept showing the previous account's 2FA state, app passwords
and API keys, and "Remove" sent that account's credential ids through
the new account's session.
`clearAllStores` now resets the store, so the page re-probes and loads
the new account, and its fetches drop answers that arrive after the
stores were cleared for another account.
