Adds field to provide detecting successful students on previous stage

There is a problem at the standard (STL) realization: it doesn't work with assoc arrays, so [0 => 123, 5 => 123] is transformed into [0 => 123, 1 => 123].

`Arr::shuffle_assoc` saves keys.

This func have the same behaviour as `as_array` function, but the last one make array of [keys => arrays].

`groupByUniqueKey` just an array of [unique key => array].
