treat research lead co-PIs position as project director

[thatbudakguy]

for geniza we're adding a new "co-PI: Research Lead" position that should function the same as "project director" for the purpose of staff pages. all of the places that specifically look for the "project director" role should look for this one as well.

testing

anyone with the "co-PI: Research Lead" role on a grant should appear on the affiliates page (test with Marina for Geniza).
