Fix to AutoFill sql Crash Report

Fix for Crash Report: http://go/crash/reportdetail?reportid=7ea9ff0f4697aa57
The AutoFill sql assertion logic was constructing an std::string from 0 when invalid data was encountered.  This caused a c++ exception and then program termination.  Correct logic is to return empty string.  Note, this fix does not address the underlying database corruption, only the crash.
