Build new_services more carefully

Build new_services more carefully

Some services that were not actually new were being considered as such because their annotations hadn't been processed as attributes yet - this occurred specifically in drag-and-drop scenarios.  The checks to building the new_services list are now more stringent.

Code LGTM, qa good, but as I said on IRC, when I reverted the changes to
service.js, the new test changes you made still passed.  It doesn't seem the
test change catches the regression.  If you could address that, then please land
it.  Thank you!
