Allow GibbsNew to fully utilize sampler state by enforcing more strict state handling after target setting #427

Currently GibbsNew reinitializes the sub-samplers after setting initial_point and initial_scale. Instead each sub-sampler should allow changing target without needed to reinitialize. This must be unit tested for each sampler.
