Removed unused renderStatus() from PhabricatorProjectSubprojectsController

Summary:
rPfc9db6e2a2ee929f56eb40530bb6f1fc1b75f563 introduced `private function renderStatus()`.
All calls to this method were removed in rP29cfcc82ef7f84580e798aebeb2abcb8ffec57d7.
Thus remove this unused method.

Test Plan: Read/grep the code in `PhabricatorProjectSubprojectsController`.
