Fix checkKeyIntentParceledCorrectly's bypass
The checkKeyIntentParceledCorrectly method was added in checkKeyIntent, which was originaly only invoked when AccountManagerService deserializes the KEY_INTENT value as not NULL. However, due to the self-changing bundle technique in Parcel mismatch problems, the Intent value can change after reparceling; hence would bypass the added checkKeyIntentParceledCorrectly call.
This CL did the following:
- Ensure the checkKeyIntent method is also called when result.getParcelable(AccountManager.KEY_INTENT) == null.
