Now calling s.next() should point to the last KV - kv5.
Before calling s.next() it would have done a moveToPrevious since there is no KV that exactly matches with the toSeek key.
Incase of NONE, PREFIX, DIFF, FAST_DIFF things work fine as expected.
But in case of Prefix Tree, calling reseek() points to a key that is same as the toSeek key which does not exist at all.
Will attach a testcase that shows this problem.
