Tests: try_files with proxying without URI part.

Proxying without URI part uses original unparsed URI if available, yet
since try_files modifies the effective URI, it should use the modified URI
after try_files.  This is what used to happen if the URI was rewritten
or changed by an index redirection, and then modified by try_files.
