rAc: don't DCHECK() when switching from Wallet -> Autofill with only 1 name.

This can happen after the account_chooser_model has been changed to the new data
source but before all the suggestions have been updated.  In this small amount
of time we snapshot SECTION_CC_BILLING while the account chooser doesn't have
wallet selected.
