Bug 22357: Do not duplicate report rows if several reports exist

At the moment every time you run runreport.pl with the --store-results
option another line will appear for your report in the saved
reports table. This is not a data, but a display problem as the
report is still only stored once.

1) Create a report and note the report number
2) Run from command line (replace X by report number) :
    misc/cronjobs/runreport.pl X --format=csv --csv-header --store-results
3) Go to saved reports table
4) Look at the table, each run of the cronjob will create a new row
   in the table instead of just updating the saved results column.
5) Apply patch
6) Veriy the table displays correctly again and there are no regressions
