Bug 26165: Fix duplication of large saved reports

If the combined character length of a saved report's
title, notes and SQL is too long then pressing the
'duplicate' button will lead to an error:

"Request-URI Too Long
The requested URL's length exceeds the capacity limit
for this server."

Test plan:
1. Create a simple SQL report and add a lot of text
   into the notes field (the combined URL lenth must be
   >8225 characters)
2. Save the report
3. Press the duplicate the report from the saved reports page
