Checks whether a message identified by the `store` , `folder_id` and `uid` is included in the index `self` .

Note the `store` is not referenced, it's compared pointer-wise, thus when a different instance of the same service as the one used in the `camel_store_search_index_add()` is used here, the message reference will not be found.
