Title: Fix NPE during loading matrix job

I am sorry my pull request 508 broke loading of MatrixProject. I did not realize that a method updateTransientActions() is called during loading of a MatrixProject before its configurations are established (an attribute activeConfiguratins is transient) so method getActiveConfigurations() return null.
