Uncorrect roster after auto-reconnect

Sometimes (well i have seen it once, today) Spark is not showing correct roster (some contacts are missing) after auto-reconnect. Today it happened after i have restarted Openfire server. Exodus and Spark have logged in almost simultaneosly and Exodus was showing everything fine. Spark 2.5.8 Beta 1, Openfire 3.4.1

hrd to reproduce and i havent seen it for a while
