Probably fix issue with creating module descriptor for SDK twice

During creation and initialization of module descriptor for sdk
  in IdeaResolverForProject.BuiltInsCache.getOrCreateIfNeeded
  AbstractResolverForProject asks for sdk dependency for module
  descriptor for this sdk, so sometimes this module descriptor was
  created twice
