EJB: don't invoke constructor on proxy creation

WFLY-11566 made component class a super class of proxy in order to help with validation problems. This leads to a side effect bug in which each proxy creation runs (f.e. as a result of view construction) leads to component constructor invocation. This should have no effect on specification related EJBs behavior cause the components themselves are created and injected correctly as a part of another process. Nevertheless, this bug needs to be eliminated.
