Modifying CentralAuthUser->attemptAutoMigration to allow for home wiki specification.

Checks to see if mHomeWiki is set and, if so, does not determine the home wiki
using chooseHomeWiki().  This allows us to set the home wiki in migrateAccount
before running attemptAutoMigration ensuring that the correct account wins.
