Fix missing function argument of getFilterQuery

In getEventMetrics no `column` argument is passed to getFilterQuery.
Thus, the subsequent arguments are shifted by one. This leads to wrong
API responses, since the filters are not properly applied.

One option is to pass a null value as the `column` argument. However, it
is not used in getFilterQuery. Therefore, I removed it.
