URL to report in footer of an exported PDF not correct

[fniessink]

For example, if the report URL is http://www.quality-time.example.org/example-report-quality-time, then the URL in the exported PDF will point to http://www/example-report-quality-time. This makes sense as that is the URL that the renderer uses to open the report.

In other environments, we see the correct URL except for the addition of a port, e.g. http://www.quality-time.example.org/example-report-quality-time becomes http://www.quality-time.example.org:2016/example-report-quality-time.

Solution: user browser frontend passes its window.location.href as extra query parameter to the server (via get_report_pdf(). The server in turn passes the parameters to the headless browser in the renderer. The frontend then uses the passed parameter in Footer.AboutReportColumn.

Also check the PDF export via the API.
