* [CHD-3833] [Support Center/History] Fixed an issue in the Support Center where the ticket history may not show the full results when multiple accounts are sharing their history and have recipients in common on the same tickets.  The database was returning duplicate tickets in these situations, which Cerb was condensing to only distinct records.  If the number of distinct results was fewer than the page limit then no additional pages were shown.
