Title: Fix saving of -1 index from keys column in array_column function

Current implementation of array_column function does not allow saving of -1 index as a key. See http://3v4l.org/fT1th (the next index is used in place of -1). This patch fixes the problem. I also added new test array_column_minus_one_index.phpt . All other tests for arrray_column passed as well.
