Fix bintray upload script (#353)

Summary:
I feel like I'm having a Groundhog Day moment. Haven't I fixed this
before?

Anyway, the release script fails (very verbosely) with an NPE
(https://circleci.com/gh/facebook/flipper/467?utm_campaign=workflow-failed&utm_medium=email&utm_source=notification)
when you run it on the root project. So we need to specify the
sub-projects we want to run it on.
