Emails: Use AccountIndex only as fallback

Due to an inconsistency in the account data in Gerrit, there are
accounts that have a primary email address without an external ID
associated with them. When looking up accounts by primary email, we
therefore have to fall back to the AccountIndex.

This commit changes the behavior from chaining requests to the
ExternalIdCache with requests to the AccountIndex to be a pure fallback
to the AccountIndex for emails that did not already find a match.
