Last week I added intra-eNB handover that works with CA enabled and tested
that all cases of intra/inter-eNB and intra/inter-frequency handover work
correctly when triggered manually. Also I made sure that all SCells are
properly released in RRC handover message (connection reconfiguration with
mobility control info) and added after handover (another connection
reconfiguration message). SCellToRelease list is properly serialized now so
all tests work with both real and ideal RRC.
