[BACKLOG-15223] Fixing DET tooltip to use the absLabel of variables, … (#6)

* [BACKLOG-15223] Fixing DET tooltip to use the absLabel of variables, when available.
Also changed the caption of discrete roles to only contain the labels of dimensions whose value is not null.

* [BACKLOG-15223] Added missing `this`, in the recent BACKLOG-15575 commit, but that was in DET version.
Fixed formatting of getPlotMapping (also already fixed in DET version, but not here).
