Bug 16281: [Follow-up] Remove the use of "onclick" from Reports module

This minor follow-up adds a dummy href attribute to the "Return to the
previous page" link so that the link behaves like a link. A
"preventDefault()" is added to the goback() function to keep the "#"
link from triggering a page jump.

To test, apply the patch, create a report with an SQL error and run
it. Confirm that the 'Return to previous page' link works as expected.
