source url bugfix: extractData exception caused url to be not saved
source url bugfix: extractData exception caused url to be not saved

Because the source_url was calculated after the call to extractData()
within the same try-block, an exception in the module code caused the
source url to be not displayed, contrary to the goal of the new concpt.

The code was moved to the upper level try-block, before the call to
extractData().
