Fix a hidden input ID issue mucking with project edits

Summary:
In D1926 this got converted to use the new InsetView, but we lost the 'id="resources"' on the hidden input which is required by the JS.

Just use phutil_render_tag() to make sure the `id` shows up.

Test Plan: Edited a project without bumping into an exception.
