SSDM-3184 : BSSE#1046539 - data set registration problem reported by Aaron - searching for a component sample by an identifier with a missing container code should be possible if the component code is unique, e.g. component COMPONENT in container CONTAINER and space SPACE should be found for /SPACE/COMPONENT identifier if COMPONENT code is unique (no other sample has such a code). The full identifier, i.e. /SPACE/CONTAINER:COMPONENT should always work. Such a behavior was originally introduced in SampleDAO.tryFindByCodeAndSpace in year 2010.
