Use only FIP dependencies from graph

This patch contains follow important changes:
 - Fix wrong parameter passsed in graph method.
 - Now we use only FIP dependencies from graph.
 - Tests were fixed according to correct logic. Previously we try to add
   router interface to FIP dependecies, when FIPAssociation was defined
   in template. It was incorrect, because in this case such dependecy
   should be added to FIPAssociation insteaf of FIP resource.
