split load-time project structure scope resolution into two phases 

first phase resolves referenced build URIs as each build is loaded
second phase resolves references without an explicit project ID
  (this requires the whole structure to be known and this isn't available during the first phase)
setting resolution is unchanged (done after both phases)
