deref_tag() prints a warning if the object that a tag refers to does not exist. However, when a partial clone has an annotated tag from its promisor remote, but not the object that it refers to, printing a warning on such a tag is incorrect. This occurs, for example, when the checkout that happens after a partial clone causes some objects to be fetched - and as part of the fetch, all local refs are read. The test included in this patch demonstrates this situation. Therefore, do not print a warning in this case.
