Fix applying createdat less or equal to rollout group filter

in case of x OR y, and createdAt <= was applied to y condition

More detailed:

The problem was that createdAt < rollout.getCreatedAt() was applied to the query with:

query + ";createdat=le=" + createdAt

But if you have 'attrib.x = 1 OR attrib.y = 2' the actual condition becomes 'attrib.x = 1 OR attrib.y = 2;createdat=le=132423'. Then the created at is applied to the attrib.y = 2 with priority. Thus

first breaks the expectations - could involve targets with createdAt > 132423 if match 'attrib.x = 1'
than it leads to joining sp_target_attributes twice with OR witch could severely impact performance
