core: ReconstructMasterParameters - return removed initialization

In change I3bb06f63b6fae8d4bc0c2b931cbfeb6b71a023a9, the initialization
of the member privateNewMasterDomainId has been moved to the ctor. The
issue is that the initialization was placed only in some of the ctors
leading the unexpected behaviour when reconstruct is executed.
