Namespace all column references in ProjectQuery to fix ambiguity with Ferret constraints

Summary:
Fixes T13378. If we join Ferret tables and page, we can end up with an ambiguous `id` column here.

Explicitly refer to "project.x" in all cases that we're interacting with the project table.

Test Plan:
- Changed page size to 3.
- Issued a Projects query for "~e", matching more than 3 results.
- Clicked "Next Page".
- Before: ambiguous id column fatal.
- After: next page.
