Fix NPE in UpdateReq.reconfigure()
While running CSIT to test heartbeat changes with multiple PAPs, observed an NPE in UpdateReq.reconfigure(). Modified the code to always use deployment lists instead of null lists. Issue-ID: POLICY-3460 Change-Id: I884e091817e88309330139a01d060e286bd42008 Signed-off-by: Jim Hahn <jrh3@att.com>
