The host scopes recent & out_of_sync allow a sql generathion with an ambiguous column name when the host has a facet with a "last_report" column and scoped search is used.

Can be reproduced by searching for something on the dashboard and having a plugin (Omaha) installed, that has a facet with a "last_report" column.
