Downgrade org.reflections to 0.9.11 due to a bug

Apparently I'm able to invoke our codepropertygraph's console via a path
that triggers ronmamo/reflections#273.
This is very unfortunate and due to the way the artifact is being
publishes I'm unable to downgrade directly in the project I use.

The fix is in 0.9.13-SNAPSHOT (not yet released) so suggestig to
downgrade until it is officially out.
