Title: [FIXED JENKINS-20506] expose SubProjectsAction also for maven projects

Subprojects are not displayed for maven projects...
I created a TransientProjectActionFactory to create the SubProjectsAction for maven projects on the fly, now the subprojects are displayed the same way as for Freestyle projects.
