Remove Default report filter for Support - Tickets dataset

The newly added default report filter for the support-tickets dataset needs to either be undone or give users the ability to turn this function off. 

Not every report created is limited to data from the past 30 days. I regularly create reports for all history or specific date ranges. I have never needed to look at the past 30 days worth of data. 

By setting this as a default feature, it creates more work for Explore users as they have to remove the filter. If they do not realize the filter is in place (depending on the visualization type, it's not immediately obvious the filter is on), this could also create inaccurate reports. Inaccurate reporting could have serious business impacts.
