Wrong getPrev() with "0|000000:"

[Roman991]

The first position is alway "0|000000:"

If u ask getPrev() on this position u will have alway the same "0|000000:"

This leads to subsequent errors as there are equal ranks in db

Hello!
Usually a first position in rank (in database table) is the middle rank LexoRank.middle();
When you use getPrev for first position you can switch to next bucket. For example rank.inNextBucket
