AMP plugin has had some updates

Offline message retrieval has been slightly changed to use different methods. If you are using the below configuration:

sess-man/plugins-conf/http\://jabber.org/protocol/offline/amp-repo-class=tigase.archive.unified.db.JDBCFlexibleOfflineMessageRetrievalRepository
sess-man/plugins-conf/amp/amp-repo-class=tigase.archive.unified.db.JDBCFlexibleOfflineMessageRetrievalRepository

Replace it with these settings to use proper retrieval method.
