Subject: [PATCH] Fixing pagination issue when using _p & _size

When using _p ang _size query params in URL, the first row is skipped.

Example:
_p = 1 & _size = 20
reqParams._index will be = (1 - 1) * 20 + 1 = 1;
Generated SQL will be SELECT * FROM ? LIMIT 1,20. This SQL skips first element (with index 0)
Correct SQL that should be generated is SELECT * FROM ? LIMIT 0,20
