Fix the filters in Calendar when use conditions with custom fiedls.

If you have custom fields in Events (tabid = 16) and try to save any filter wher in conditions you have a custom field, don't charge this fields in $modulefields array because the query just search the fields for tabid = 9 (Calendar) and don't return the custom fieds for Events.
