[549918] Fix ClassCastException when selecting a tool in a diagram extension

This reverts commit 2a2a7ee1921adeed877a1a8b877212e745878ce6, which
can cause ClassCastExceptions: the two code blocks that were merged
into one were not exactly the same, one handled
RepresentationDescription (and casts to that), and the other handles
RepresentationExtensionDescription, which can *not* be cast to
RepresentationDescription.
