Fix UUID mismatch

There were two ways to fix this: Use consistently either UUID "c1bb..."
or UUID "5909...".

From the document it was pretty clear that "c1bb..." is the correct
UUID.  First, this unit is referenced by "c1bb..." at other places.
Second, there is already another feature with UUID "5909...".
