It was caused by the fact that we show the combined starred mailbox
on each account's mailbox list.
Beacuse of this, when you open the starred mailbox on non-combined view,
we pass a normal account ID + the combined starred mailbox ID to the
AccountsLoader, which then thinks that because the account ID is not
ACCOUNT_ID_COMBINED_VIEW the mailbox ID must be of a regular mailbox,
issues a query to get mailbox info, and crashes because the mailbox
is virtual.
- Also fixed the issue that we don't show message count on the account
spinner for combined mailboxes.
