Hold the tree tests to a working page

The tree requests passed on any answer short of a crash. Several tests
read a page or a row an earlier test wrote, so run alone they passed
or failed by accident, and two leant on a repository from the test
before without saying so. The file-50 check also matched its href, and
the blame check skipped the form feed and NEL its title covers.
