[SP-290] Patch request for PRD-4527 - Changing auto submit on PRPT gives "error parsing parameters" when report added to dashboard

* Fixes report content not showing when refresh is triggered by a parameter change and auto-submit is true. This is an issue created by the previous fix for PRD-4527.

@rfellows please review this additional fix, that I had done more recently to 4.5 and 4.8 (at 1 Out.).
