Add test id and/or timestamp to page result title

[bwbroersma]

Currently the title is: Website test: ${test_hostname}.

📋 Chrome by default has the OmniboxCanCopyHyperlinksToClipboard feature, that uses the title in a rich HTML Clipboard Format:
<a href="${location.href}">${document.title} (${location.hostname})</a>, so:
<a href="https://${instance_hostname}/website/$test_id/${test_hostname}/">Website test: ${test_hostname} (${instance_hostname}</a>.
Maybe change the report title to include a timestamp and test id?
E.g. Website test: ${test_hostname} (#${test_id} - ${rfc3339timestamp})?

🖨️ Firefox and Edge/Chrome use this in the PDF print name, where : is converted to _.
For at least the PDF print name it would be great to not have the : (_) and have a RFC3339 timestamp prefixed together with test id. Maybe even include instance name. So just before printing, I would propose to change the document.title to:
${rfc3339timestamp}-website-test-${test_id}-${test_hostname} or
${rfc3339timestamp}-${instance_hostname}-website-test-${test_id}-${test_hostname}
This can be done with the beforeprint event.
