Sergey Vojtovich 0acdf23f16 BUG#39185 - Cardinality for merge tables calculated incorrectly. 
Every subsequent query to a merge table with indexes was lowering
down cardinality.

The problem was that key statistics was not cleared when merge
children were detached. Causing next attach children perform
incremental key statistics calculation.

Fixed by clearing key statistics when attaching first child.
