Test coverage for restricted issues search

[labkey-klum]

Rationale

This adds test automation to ensure expected behavior when searching for restricted issues:

• Issues that a user doesn't necessarily have access to should still appear in the search listing
• Search details link should display an error page if the user doesn't have access

Thanks for asking @brentlogan. The fix this PR is testing is a pretty straight forward fix in platform that we've tested and believe is low risk of any issues. It's also a little more challenging to get you a platform feature branch installer. Can you test on one of your test servers after we merge it in? We can quickly backout the change if there's something that isn't matching your expectations.
