Add on_winner_choose hook

…ontrol

When using allow_multiple_experiments=control Split only allows one
experiment with an alternative other than 'control'.

Split::User#max_experiments_reached? checks for that looping through all
experiments. As Split::User#active_experiments drops the experiment
version we also need to do that here to be able to check properly.

Fixes #612
