PreferenceMigrator force commits pref upgrades.

Now, when PreferenceMigrator.migrate is run,
we forcibly call commit after the VersionedPrefs
object is updated (whether MailPrefs, AccountPreferences
or FolderPreferences). This commit applies the change to
Email2. Should fix b/8640441 and b/8520847.
